What it is / What it does:
Transporter - The Transporter is a Transposition device used primarily for the safe and almost
    instantaneous transport of personnel and hardware.
    The transporter was Gene Roddenberry's solution to the television
    production problem of how to get his characters from the starship
    down to a planet's surface.  Landing a huge spaceship every week
    would  have cost  far too much  for a  television budget,  but  the
    transporter provided an ingenious means of getting the characters
    quickly (and inexpensively) into the midst of the action.

    The transporter is an energy-matter scrambler.  The molecules in your body
    are: converted into energy, then beamed into the transporter chamber
    and reconverted back into their original pattern.
                        "The Savage Curtain" [TOS]

     You are conscious during transport.  Further, while in transport, you appear
    whole to yourself.
                        "The Wrath of Khan" [ST2], "Realm of Fear" [TNG]

     It's hypothesized that the annular confinement beam first locks onto,
    then disassembles the
subject into phased matter, via the phase transition coils, causing it to
    take on a very
energy-like state somewhat akin to plasma, called phased matter.  This is why
    it is often
thought of as a matter to energy conversion.  The matter stream is then fed into the
buffer, piped through waveguide conduits to one of the beam emitters on the hull of the
    starship, and then relayed (or "beamed") to a point on the ground where the ACB reconstructs
    the subject.

  The NX-01's transporter is located directly off a corridor on D Deck.                 

    The transporter is a device that compresses the molecular components of an object into a
    datastream and beams it to another location. It has only recently been approved for biotransport,
    a fact that the crew members are uncomfortable with. It has been said that Captain Archer
    wouldn't even put his dog, Porthos, through the transporter.
                                                   "Broken Bow" [ENT]

Ryan refers to rumors about transport of humans: that for a split second, you can feel yourself in both locations.
    Travis implies this is why he's anxious to try it, although most of Enterprise's crew is afraid.
                                                     "Fortunate Son" [ENT]


Visual / Auditory Effects:

22nd century Starfleet transporter effect consists of a number of blue-tinged white sparkles, with a vertical
    sweep and a swirl at the center, moving to one center forming a small sphere that then disappears - as
    though the matter were going down (or coming up from) a drain.  The effect takes about 3 seconds. 
    The transporter can be recycled, from "receive" to "transmit", almost immediately -- about 3 seconds.
                                                     "Civilization" [ENT]

23rd century Federation transporters during the 2260s showed a shower of golden "sparkles" during
    materialization and dematerialization. Klingon units during the same time emitted a solid golden "haze"

By the 2280s, both races utilized transporters that appeared to utilize a "wave" effect. The Federation's
    being blue and the Klingons with golden yellow.

24th century Federation transporters emitted a distinct blue/white "sparkle" when used. Klingon transporters
    displayed a red/orange sparkle and Romulan transporters a green sparkle. Cardassian and Ferengi
    displayed red/orange "swirls" of energy. Borg displayed green "swirls" of energy.

Another difference was the speed by which a transporter operates. Compared to transporters used by the
    Hunters, a Gamma Quadrant species, in 2369, the Federation transporter was slow.
                                                                    "Captive Pursuit" [DS9]

Furthermore, each type of transporter beam had a distinctive sound pattern associated with it. Along with
    differences in "tone," the volume of the sound also varied. Klingon transporters in the 2260s, for example,
    were completely silent.

History and Development of the Transporter:

Transporters have been used by many alien civilizations down through history.

ca. 2120:  A fact commonly perceived as a continuity error is that the Human colonists on Moab IV
    appeared to be stunned by transporter technology, despite the fact that their colony was founded
    "200 years ago". Taking this rather vague statement exactly, it would mean that the inhabitants
    of Moab IV did not know of the technology in 2168, 30 years after standard-transporters must
    have been invented and 15 years after they were frequently used on the Enterprise (NX-01).
    However, it is absolutely reasonable to assume that the 200-years statement was an approximation,
    meaning the colony could have easily been founded 210 or 215 years ago. Furthermore, it is
    possible that the founders of the colony left Earth even earlier, and it took them 10 or 15 years
    to get to the planet when colonization officially started.  This could put the time they actually left
    Earth back to a point when the Human public was still not aware of the brand new transporter
    technology.  Also putting the founders closer to the Eugenics era makes sense since for a time
    many people still had ideas that mankind could be improved by genetic engineering - the basic
    philosophy of their society ("The Augments" [ENT]).
                                                             "The Masterpiece Society" [TNG]

sometime before 2126:  The first human transporter is invented by Emory Erickson. who becomes known
    as "The Father of the Transporter".  When he was 7 years old, a book with that title was given to
    Trip Tucker.  It inspired him to become an engineer.  (Trip was 7 years old in 2126)
                                                              "Daedalus" [ENT]

    During the initial tests for the transporter, some brave men and women were lost.
                                                              "Daedalus" [ENT]

ca. 2130:  The Terratins were descendants of an early lost earth colony, initially designated "Terra Ten".
    (perhaps this was the tenth of a series of "Terra-" colonies - Terra Nova might have been the first).
    Since the intersat code that they used to contact the Enterprise hadn't been used for two centuries,
    it is often assumed that their colony can be dated from that time - two centuries before 2269 would
    be ca. 2069.  This can't be the case since the Terratins had knowledge of starship methods and
    transporter technologies, and humans didn't have a working transporter back in 2069.  It is more
    likely they were just using an outdated communication code, and that the colony actually dates to shortly
    after the transporter was invented.       "The Terratin Incident" [TAS]

ca. 2139:  Emory and his son Quinn were conducting first trials... "Emory's greatest achievement"...
    a subquantum transporter.  Quinn wanted to be the first to go through.  Emory lost his signal and
    couldn't get it back.  Quinn's transporter signal became trapped in a region known as the Barrens.
                                                              "Daedalus" [ENT]

There were protests when the transporter was first approved for bio-matter...  People said it was
    unsafe, that it caused brain cancer, psychosis... and even sleep disorders.  And then there was
    all that metaphysical chatter about whether or not the person who arrived after the transport
    was the same person who left and not some weird copy. 
                                                                "Daedalus" [ENT]
The original transporter took a full minute and a half to cycle through.  It felt like a year.
    You could actually feel yourself being taken apart and put back together.
                                                                "Daedalus" [ENT]

2151:  The Enterprise NX-01 was one of the first Starfleet starships to be equipped with a transporter
    authorized for transporting biological objects.  At this point in time many people still don't trust the
    technology and use it for biological transport only sparingly.
                                                                "Broken Bow" [ENT]

2154:  The transporter on the NX-01 is upgraded.
                                                                "Daedalus" [ENT]

2209:  Transporter psychosis is first diagnosed by researchers on planet Delinia II.
                                                                "Realm of Fear" [TNG]

2319:   The problem causing Transporter psychosis was eliminated with the development of the
    multiplex pattern buffer.                     "Realm of Fear" [TNG]

24th century:  Safer site-to-site transport is developed.

29th century:  A temporal transporter is in use.

Types of Transporters:

[ Personnel ][ Cargo ][ Portable ][ Emergency ][ Micro-transporter ][ Temporal ][ Subquantum ]
[ Alien Transporters ]

Personnel Transporter:

The most commonly used type of transporter was the personnel transporter, designed primarily for personnel.

Transporter platforms had a variable number of pads, arranged in various layouts (by model and by
    manufacturing race):

The transporters installed on Earth's NX-class starships featured one large circular pad that took up
    the entire platform. It was large enough to transport 2-3 people provided they stood close together.

By the 23rd century, Federation transporter platforms featured multiple independent pads, typically six in
    a hexagonal configuration. One- and two-pad platforms were also available.

This would become something of a standard layout for Federation transporters well into the next century.
    As an example, the platforms used on board Galaxy starships had the familiar six individual pads with
    an oversized pad in the center of the platform that could handle small cargo.

The model of transporter installed on board Defiant starships featured a circle platform and three
    personnel pads in a triangular formation.

Some 23rd century Klingon platforms featured 6 hexagonal pads in a straight line. Others, such as those
    on Birds of Prey, featured a small number of platforms in a tight group.
                                                            "The Voyage Home" [ST4], Star trek VI: The Undiscovered Country)

Cardassian transporter pads in the 24th century featured three to five triangular pads placed close together,
    such as those installed on Deep Space 9.

The personnel transporter was a reliable but sometimes fragile piece of equipment. The phase coils in
    particular were vulnerable to feedback patterns and could be severely damaged as result of power
    surges or low-level phaser fire.

Cargo Transporter:

Cargo transporters were larger scale versions of personnel transporters and were optimized for the
    transport of inanimate objects.

In case of an emergency, cargo transporters could be reset to quantum-level mode, making lifeform
    transport possible. These transporters were adapted to handle massive quantities of material.
                                                            (TNG|Up The Long Ladder)

Cargo transporters were also specialized for transporting hazardous material and were mostly found
    inside the cargo bay of a starship or space station. (TNG|Evolution)

Dedicated cargo transporter platforms used by Starfleet in the 24th century typically featured one large
    circular or oblong pad. Some had additional standard-size "personal" pads as well.

Emergency Transporters:

In older technical manuals and other non-canon background materials, these are sometimes
    referred to as "evacuation" transporters or "combat" transporters. Typically, they are said
    to be platforms with a dozen or more pads each. In addition to emergency evacuation, they
    are used in
any high-volume movement of personnel, such as in troop deployment.

Emergency transporters are a special type that can only beam someone from a ship or space station,
    not usually the other way around. Emergency transporters have a low power requirement; in case
    of a shipwide power failure, the crew could use these transporters for emergency evacuation.
                                                            (TNG Technical Manual)

By the late 24th century, emergency transport was further improved through development of a
    single-person, single-use, one-way emergency transport unit. The device was small enough to be
    hand-held and could transport to specified coordinates with a single touch.  Because of its extreme
    limitations, this device was not widely deployed and was still considered a prototype in 2379.
                                                            (Star Trek: Nemesis)

Sub-quantum teleportation
    you step on to a transporter on Earth... a few seconds later, you're on Vulcan.  That's over
    16 light-years.  That's just for starters.  Theoretically, there's no limit to the distance.
    The Vulcan Science Academy has been studying sub-quantum transporting for some time...
    with little result.

Subspace Transporter:  In "Bloodlines" [TNG], Bok has a subspace transporter, a technology which
    was researched but later abandoned by the Federation. The range is at least 300 billion kilometers,
    and at most several light years and the subject is put into a state of molecular flux. Doesn't sound
    healthy. How is this different than normal transport? Probably just a deeper level of subspace.

Folded Space Transporter:  In "The High Ground" [TNG], transporting through folded space using a
    subspace field coil made for instant, untraceable transports. The only problem is that it causes slow,
    irreversible genetic damage to the transport subject. It is a cumulative effect: one or two transports
    would be harmless, but dozens or hundreds are fatal. The Federation experimented with such
    technology in the 23rd Century, so this may be what Bok was using as well.

Transporter Components:
[ Abort Control Circuit ][ Annular Confinement Beam ][ Autosequencers ][ Beam ][ Biofilter ]
[ Carrier Wave ][ Coadjutor ][ Heisenberg Compensator ][ Unit Ionizer ][ Main Circuits ][ Matter Stream ]
[ Pattern Buffer ][ Pattern Lock ][ Phase Transition Coils ][ Phased Matter ][ Rematerialization subroutine ]
[ Targetting Scanners ]

Main Circuits - The main circuits for the transporter are inside a casing on the lower level
Abort Control Circuits    of Engineering.  The "evil Kirk" accidently burned through them with a
    phaser disabling the transporter again.  The abort control circuit
    was gone altogether.  The transporter unit ionizer appears to have
    been damaged as well, with nothing much left of it.  Original estimates
    were that the damage couldn't be repaired in less than a week.  But
    they did manage to get the transporter working in less than a day by
    attaching to some bypass and leader circuits to compensate for the
    difference, tied directly into the impulse engines.  It was estimated
    that there shouldn't be more than a 5-point variation in the velocity balance.
                                                                 "The Enemy Within" [TOS]

Annular confinement beam - Abbreviated as ACB.
    A cylindrical force field used to ensure that a person being transported remains within the beam.
                                                                "Power Play" [TNG]
     The Confinement Beam Subsystems check out during complete diagnostic.
                                                                "Realm of Fear" [TNG]
Breach in the ACB:
    Failure to remain within the confinement field can cause a dangerous release of beam energy,
    possibly fatally injuring the transport subject and those nearby.  Roga Danar, during transport from
    a security holding area to an Angosian police ship, deliberately disrupted the ACB, causing a blast
    of energy that permitted him to escape.  "The Hunted" [TNG]
    There is a breach in the annular confinement beam when Torres tries to beam samples from the protostar.
                                                                 "Heroes and Demons" [VOY]
Narrowing the Beam:
    Kim tells Hogan to try narrowing the annular confinement beam when they are beaming up Tuvok and Neelix.
                                                                 "Tuvix" [VOY]
    When trying to beam the deuterium from the planet, Seven tells Nozawa to narrow the annular confinement
    beam to .47 terrahertz.                           "Demon" [VOY]
Boosting Power to the Beam:
    When Picard was trapped on the surface of El-Adrel IV in 2368, La Forge attempted to boost the ACB
    in an effort to penetrate the particle scattering field that surrounded the planet.
                                                                 "Darmok" [TNG]
    Kim boosts the power to this when he is unable to beam Neelix, Arridor and Kol off the planet.
                                                                "False Profits" [VOY]

Autosequencer - A subsystem of a starship's transporter that controls the actual transport process.
    It must be brought online prior to the transporter's use.
                                                               "Broken Bow" [ENT]
    A possible autosequencer malfunction was investigated following the apparent transporter-related
    death of Ambassador T'Pel in 2367. It was later found that T'Pel was not dead and that her real name
    was Subcommander Selok.  She had faked the malfunction to cover her escape into Romulan hands.
                                                                "Data's Day" [TNG]

Beam: May be confused with ACB.
    Borg scatter the transporter beam         "Scorpion, part 1" [VOY]
    The transporter beam ignites the proto-matter.
                                                                 "Mortal Coil" [VOY]

Biofilter -
    Biofilters were uniformly used on all Federation transporters by the 24th century.
    These filters functioned to decontaminate transported objects and prevent harmful substances,
        pathogens, and even certain forms of radiation (including theta radiation), from contaminating the
        rest of the ship.                                 (VOY|Macrocosm|Night)
    Though biofilters performed a general contaminate removal with each transport, some novel contaminate
        removal required specific calibration in order for the filters to be effective. As such, biofilters were
        incapable of filtering out certain types of substances and pathogens, most notably psychic energy.
                                                                (TNG|Lonely Among Us|Power Play)
    Biofilters were also unable to detect and filter certain types of phased reality lifeforms without prior
        calibration. Biofilters also functioned to detect and disable weapons and explosives (remat detonators).

Pattern Buffer - the multiplex pattern buffer was developed around 2319 which eliminated the
     problem of transporter psychosis. "Realm of Fear" [TNG]
     A 29th century tricorder was used to overload the pattern buffer.
                                                            "Future's End, part 2" [VOY]
     A macro-virus migrated into the pattern buffer.
                                                            "Macrocosm" [VOY]
     Odo channeled an explosion into the pattern buffer on the USS Rio Grande.
                                                            "The Ascent" [DS9]
     The main transporter buffer was damaged when Voyager went through the spatial rift so they
         were unable to use the transporter at long range.
                                                            "Future's End, part 1" [VOY]
    Hoshi became trapped in the pattern buffer for 8.3 seconds causing some trouble in reintegrating
       her matter stream.  It is likely the last couple of seconds as the matter stream was coelessing
       is when she suffered her hallucinations.
                                                            "Vanishing Point" [ENT]

The pattern buffer is a key component of the transporter system. The buffer is used to temporarily store the matter stream, following dematerialization, but prior to sending the stream to its target. This is done because of the relative motion of transporter and target. By temporarily storing the matter stream, the Doppler compensators have the time to adjust the targeting scanners.

A matter stream cannot be stored indefinitely in the buffer; after 420 seconds, the stored pattern will degrade and the object will be lost. The only known record of a person surviving in a buffer longer than the expected figure was Captain Montgomery Scott on board the USS Jenolan. Following the Jenolan's crash-landing on a Dyson sphere, Scott, with the help of Matt Franklin, was able to store his pattern in the buffer for 75 years. This was achieved by disabling the rematerialization subroutine, connecting the phase inducers to the emitter array, bypassing the override, and locking the buffer into a continuous diagnostic cycle. Although Captain Scott's pattern suffered less than 0.003% degradation, and was successfully recovered by Geordi La Forge of the USS Enterprise-D in 2369, Franklin was irretrievable, as one of the inducers had failed, causing a 53% degradation in his pattern. (TNG: "Relics")

In 2152, diamagnetic storms saturated with polaric energy were encountered on a planet visited by the crew of the starship Enterprise. The storms interfered with the operation of the ship's transporter, resulting in Hoshi Sato being trapped in its pattern buffer for 8.3 seconds while Malcolm Reed worked to reintegrate the matter stream. (ENT: "Vanishing Point")

On Galaxy-class starships the pattern buffer is located immediately beneath the transporter pad.

When weapons were beamed to a rebel camp on Krios from a cargo transporter of the Enterprise-D in 2367, Miles O'Brien asked Geordi La Forge if he could check the reliability of the pattern buffers. (TNG: "The Mind's Eye")

When Jadzia Dax decided to stay on planet Meridian in 2371, the transporter buffer of the USS Defiant was used to bring her quantum matrix in sync with that of the Meridians. (DS9: "Meridian")

Starships can also transfer patterns from one pattern buffer to another by "locking on" to the target buffer and energizing. (VOY: "Future's End, Part II")

To eliminate the medical condition called transporter psychosis, Federation transporters are equipped with multiplex pattern buffers. (TNG: "Realm of Fear")

The transporter buffer of an Intrepid-class starship performs a version of a microcellular scan every time it is used. (VOY: "Favorite Son")

Cardassian transporter systems were still equipped with active feed pattern buffers in 2367, considered outdated by Starfleet. (TNG: "The Wounded")

In 2374, the crew of Voyager overloaded the ship's pattern buffers attempting to transport deuterium from beneath the surface of a Y-class planet. (VOY: "Demon")

Carrier wave - A subspace signal through which a transporter beam is propagated.
 Romulan transporters, with minor adjustments can be made to simulate the carrier wave
 of a Starfleet transporter.  "Data's Day" [TNG]

Coadjutor - This was engaged when the transporter tried beaming up a crewman with a magnetic ore
    contaminating his uniform.  The transporter was acting like a burn-out.
                                                                 "The Enemy Within" [TOS]

<>Console -
The transporter console is a component of the transporter system. Located in the transporter room, it
    manually controls the functions of the transporter and its maintenance. It is typically operated by the
    transporter chief or other operations division personnel.

Commonly seen aboard starships from the 22nd century all the way through the 24th century, the
    transporter console utilizes three sliding controls (either manual levers or touch sensitive panels) to
    achieve transporter function. (ENT: "Broken Bow")
During the making of both the original pilot "The Cage" and the second pilot "Where No Man Has Gone Before", Star Trek's production personnel reused the bridge helm console as the transporter console.
<><>The console allows the operator to monitor various functions of the transporter system, including pattern buffer
operations, signal resolution and even matter stream contaminants. The transporter operator
could also detect the presence of weapons or phaser fire within the transporter beam, and in some cases could deactivate the weapon before re-materialization. As yet another security feature, the console allowed the operator to erect a force field around the transporter chamber. Prior to the introduction of biofilter technology, the console controlled the activation of the system's decontamination feature.
(TOS: "The Naked Time", TNG: "Violations", "The Most Toys", "Realm of Fear", "Relics")<>

By the late 24th century, site-to-site transport became more commonplace and did not require a
    transporter console. Site-to-site transports could be activated by voice commands to the computer
    fairly easily. A site-to-site transport from a starship to another starship could also be done, from any
    console, such as a bridge station. The use of a bridge station to control transporter operations was
    a feature of some starship bridges as early as the 23rd century
                                                            (VOY: "Bliss", Star Trek Nemesis, Star Trek II: The Wrath of Khan)

By the 29th century the transporter pad has been moved to the bridge of timeships such as Wells-class ships,
    and was operated from bridge stations. (VOY: "Relativity")

Emitter Pad - Checked out during diagnostic.  O'Brien reported that it was running normally.

Heisenberg Compensator - In physics, the Heisenberg Principle states that you cannot know both
    the position of a subatomic particle and its momentum to a precise degree. The more you know about
    one, the less you know can about the other.  This comes into play when you consider that to know
    where everything is coming from and going to, you pretty much have to know near-exactly where
    everything is. By the 24th century, evidently, that's no longer a problem. The Heisenberg Compensators
    are probably used to keep everything in the matter stream exactly where it should be.  Note that this
    doesn't mean that the Heisenberg Compensators tell you the vital statistics of the particle; they could
    very well just compensate for not knowing them and keep the system working.

Imaging Scanners - If the imaging scanners are off by even a thousandth of a percent it could be bad.
    That's why each pad has four redundant scanners. If any one scanner fails, the other three take over.

Phase Transition Coils - They are called Phase Coils for short.
                                                                "Realm of Fear" [TNG]
    Phase coils are aligned using a parametric scanner.
                                                                  "Singularity" [ENT]
    According to Hoshi's hallucination, if the secondary phase coils don't align so that they are perfectly
       synchronized, the transportee's resequencing will start to dissipate so that within hours they
       will lose molecular cohesion.  Nothing would be left but subcellular residue.
                                                                "Vanishing Point" [ENT]
    Phase coils don't react well to phaser fire (or phaser richochets off force fields).
                                                                "Brothers" [TNG]
    Placing the Phase Transition Coils at standby is one step in the transport process when two
        transporter systems have been bridged.

Targetting Scanners -

Adjuncts and Extra Equipment to be used with the Transporter:

Remote Activation:
    By the 24th century, transporter systems could also be operated from computer terminals other than
    those in transporter rooms. Furthermore, emergency transporter armbands, transponders, and combadges
    could be programmed to remotely activate a transporter. Normally, remote transporter activation was
    limited to emergencies or when the crew of a vessel was not on board.

     and transport Ba'ku inhabitants in 2375, despite the fact that the Ba'ku had taken refuge in
     areas of high kelbonite concentrations.

Normal Transporter Operations:

[ Transport Sequence ][ Codes and Protocols ][ Testing and Diagnostics ]

Typical Transporter Sequence:

1.  Target Acquisition Scan / Coordinate Lock
    A typical transport sequence began with a coordinate lock, during which the destination was verified
    and programmed, via the targeting scanners. Obtaining and maintaining a transporter lock enables the
    transporter operator to know the subject's location, even in motion, allowing the beaming process to
    start more quickly. Maintaining a transporter lock is an essential safety precaution when a starship
    away team enters a potentially dangerous situation that could require an emergency beam-out.

    A transporter lock was usually maintained by tracing the homing signal of a communicator or combadge.
    When there was a risk that such devices would be lost in the field or are otherwise unavailable,
    personnel could be implanted with a subcutaneous transponder before an away mission to provide
    a means of maintaining a transporter lock. Alternatively, sensors could be used to scan for the biosign
    or energy signature of a subject, which could then be fed into the transporter's targeting scanner for a lock.

    In 2293, Spock used a viridium patch to locate and lock on to Captain Kirk and Dr. McCoy on
    Rura Penthe. While not a transporter device, it was used to locate the subject with the transporter.
                                                           "The Undiscovered Country" [ST6]
    SEE Also: Emergency Transporter Lock

2.  Confinement
        Annular Confinement refers to a transporter subsystem used to insure that a person being transported remains
        within the beam during transport.         "Broken Bow" [ENT]
         SEE: Annular Confinement Beam

     Immobilization / Suspension of Target
        From its earliest incarnations, with perhaps one or two exceptions (Kirk in the episode That Which
every instance of transporter use showed a "suspended subject".  Transporters generally
        immobilized the subject being beamed both during dematerialization and rematerialization.  These
        Old-style transporters always transported the subject under stasis. There appear to be two stages in
        the beam-out process. First, a sparkly pattern appears over the chest of the subject, and spreads to
        cover them. They are sometimes seen to move during this process. But then they start to have these
        yellow blobs appear as they fade out. They don't move during this second stage. We can speculate
        that there's a stasis field employed for some reason (technological limitations, safety, etc) during the
        actual transport stage with old technology. This style of transporter was also present on the Jenolan
        ("Relics" [TNG]), but is now obsolete.
                                                                ENT, TOS, TAS, "The Motion Picture" [ST1]        

        Advances in transporter technology some time between the early 2270s and mid 2280s, allowed a
        person being transported to move during the process in a limited fashion.  Transport subjects were
        shown being able to engage in limited movements, and even conversation while in transport.
                                                                "The Wrath of Khan" [ST2]

3.  Molecular Imaging / Quantum Level Scan
Next, the lifeform or object to be beamed was scanned on the quantum level using a molecular
        imaging scanner. At this point, Heisenberg compensators took into account the position and
        direction of all subatomic particles composing the object or individual and created a map of the
        physical structure being disassembled amounting to billions of kiloquads of data.

the transporter operation process included the use of the annular confinement beam, followed by electromagnetic focusing, the use of a gravitational compensator. Then the operator applied a temporal differential, after which he engaged a particle lock. "Star Trek" [ST2009]
The information about the alternate reality transporter process comes from on-screen graphics of the transporter control panel in several scenes in the movie.

4.  Dematerialization / Conversion to Matter Stream
Simultaneously, the object was broken down into a stream of subatomic particles, also called the
        matter stream.
5.  Storage in Pattern Buffer
The matter stream was briefly stored in a pattern buffer while the system compensates for Doppler
        shift to the destination.
6.  Transmission
        The matter stream is then transmitted to its destination via a subspace frequency. As with any type
        of transmission of energy or radiation, scattering and degradation of the signal must be monitored
        closely. The annular confinement beam (ACB) acts to maintain the integrity of the information
        contained in the beam.
7.  Rematerialization
        Finally, the initial process was reversed and the object or individual was reassembled at the destination.

Transporter Records:
Transporter ID trace - the transporter ID trace is kept for verification purposes for a long time after
    transport. This is probably a highly compressed sample of the pattern, plus the name of the transportee,
    logs of the transport cycle, etc.

    A computer record maintained by a Federation starship's transporter system, recording the identity
        of all transport subjects.  The transporter ID trace provided a useful means of verifying whether or
        not a person has actually been beamed.
                                                             "Unnatural Selection" [TNG], "Remember Me" [TNG]
    Data and Dr. Beverly Crusher compared Ambassador T'Pel's transporter ID trace to her "remains"
        left on the transporter pad after her apparent death in 2367.  The single bit errors discovered by
        this comparison proved the remains were not those of the ambassador.
                                                             "Data's Day" [TNG]
    Picard was recovered from being beamed away as pure energy. The computer was able to reconstruct
        Picard by using the pattern it had stored, working with the phased matter stream that Picard's energy
        state itself supplied. Since the pattern was pre-transport, the reformed Picard had no memories of
        the excursion.                                 "Lonely Among Us" [TNG]

Transporter log - Used to discover that Seven's borg nanoprobes have regenerated.
                                                             "The Raven" [VOY]

Transporter Signatures:

Residual ionization traces can be considered a transporter signature although that type of technology
    wasn't widespread in 2154.  Starfleet Operations satellites normally would detect and make a record
    of any transporter activity.                  "Affliction" [ENT]

Transporter Codes & Protocols:
Transporter protocol 5 - Program to disable / deactivate / remove weapons:
    By the 24th century, the transporter had the capability to disable any active weapon during transport.
        This could be accomplished by removing the discharged energy from the transporter signal,
                                                                "Datalore" [TNG]
    or by "deactivating" the weapon itself.    "The Most Toys" [TNG]
    The transporter was also capable of removing weapons entirely during transport. When the Defiant
        beamed aboard survivors from a damaged Jem'Hadar ship, the transporter was programmed to
        remove the crew's disruptors and other weapons.
                                                                "To the Death" [DS9]
    While under Romulan control in 2367, Geordi La Forge altered several isolinear chips to permit
        unauthorized use of the cargo transporter to beam weapons to the planet Krios. He also programmed
        the chips to delete all operator commands once the transport was complete, effectively erasing any
        record of the use of the transporter.
                                                             "The Mind's Eye" [TNG]
    Not all weapons could be deactivated, at least not by the older transporters.
    For example, a gravity switch would detonate in the matter stream.
                                                                "The Forge" [ENT]

Transporter Code 14 - Command for an object to be dematerialized, then immediately rematerialized
    in a dissociated condition, effectively destroying the object.  Captain Picard used Transporter Code 14
    to destroy the fabled Tox Uthat at Risa in 2366.
                                                                "Captain's Holiday" [TNG]

Because of an accident involving Hoshi Sato becoming trapped in the pattern buffer, Malcolm
    recommended some new transport protocols to Star Fleet.  He suggested that they start
    compressing the transport beam.          "Vanishing Point" [ENT]

Before an away team beams down, a number of sites may be designated for preferred transporter use
    based on their availability and how much transport interference can be expected.  For example, Chakotay
    ordered all units on the surface to report immediately to Transporter Site A to prepare to  beam back
    to Voyager.                                         "State of Flux" [VOY]

Safety Features:

One safety feature protected the transport subject to a certain degree from external influences once the
    dematerialization process had begun.
This protection extended to both high energy discharges (such as energy weapons fire)
                                                             "Broken Bow" [ENT], "A Matter of Perspective" [TNG],
                                                             "The Most Toys" [TNG], "The Undiscovered Country" [ST6]
...and physical incursions (such as projectile weapons fire).
                                                             "Bread and Circuses" [TOS]
Such protection was not infallible, however, particularly in the earlier models of transporter. "Foreign
    matter" could get caught up in the transport process and become embedded or integrated into the subject.
                                                            "Strange New World" [ENT]
However, the 22nd century had yet to perfect this method of transport when Major Joss Hayes died
    from a Xindi weapon shot.                "Countdown." [ENT]

Biofilters were uniformly used on all Federation transporters by the 24th century.
These filters functioned to decontaminate transported objects and prevent harmful substances, pathogens, and even certain forms of radiation (including theta radiation), from contaminating the rest of the ship. (VOY|Macrocosm|Night)
Though biofilters performed a general contaminate removal with each transport, some novel contaminate removal required specific calibration in order for the filters to be effective. As such, biofilters were incapable of filtering out certain types of substances and pathogens, most notably psychic energy. (TNG|Lonely Among Us|Power Play)
Biofilters were also unable to detect and filter certain types of phased reality lifeforms without prior calibration. Biofilters also functioned to detect and disable weapons and explosives (remat detonators). (TNG|Realm of Fear|The Schizoid Man)

Additionally pattern buffers were used to compensate for relative motion during transport, ensuring that transported matter materialized in the correct location.

Except in cases of extreme emergency, protocols prohibited transporting objects while traveling at warp speed. (TNG|The Schizoid Man)

Testing and Diagnostics:

Transporter diagnostic - After the transporter accident, they run a diagnostic on the transporter and
    find that everything is functioning normally. "Tuvix" [VOY]

Diagnostic / Maintennance Tools:
Magneton scanner -

Micro-resonator - Tuvok orders Chell to degauss the entire Transporter room using a micro-resonator;
    Tuvok estimates that it will take 26.3 hours.  This doesn't appear to be the normal tool used for
    degaussing the transporter room but was only being used because Tuvok was trying to get Chell
    to follow orders -- similar to a 20th century drill instructor in boot camp ordering someone to
    clean an entire bathroom using only a toothbrush.
                                                                 "Learning Curve" [VOY]
Parametric scanner - Used to align phase coils.  It was once used by Tucker to get Archer's exact
    measurements for a new captain's chair.  Tucker said that Archer wouldn't feel a thing while being
    scanned.                                                "Singularity" [ENT]
Synchronic Meter - After the transporter malfunction that looked like a burn-out, this device was used
    to double-check the transporter to make sure it was ok.  The test didn't catch the malfunction that
    caused Kirk to be split into two and duplicated.
                                                                 "The Enemy Within" [TOS]

Transporter test article - A cylinder of duranium about one meter tall and 25 centimeters in diameter.
     Used to test transporter performance by beaming the article away and then back to a
     transporter pad, or simply beaming it between pads.

    was used for quite a number of props in Star Trek:TNG).
Transporter Test cylinder - A standard starfleet mechanism with a varietal molecular matrix; it simulates

    computer data files.                             "Future's End, part 1" [VOY]

Intraship Beaming -  Method of transporting within the confines of a starship.  This procedure required
    pinpoint accuracy, running the risk of materializing the transport subjects inside a wall or deck.
    Kirk and Klingon science officer Mara risked intraship beaming to carry an offer of peace to Kang
    when the Enterprise was held captive by the Beta XII-A entity in 2268.
                                                               "Day of the Dove" [TOS]
    The technique was perfected by the time of Star Trek: The Next Generation.

Transporter stasis, also called Transporter suspension -
    Technique which involves suspending the transporter patterns of people.
                                                                'Day of the Dove' (TOS), 'Relics' (TNG)
     used by the crew of Voyager to hide telepaths from the Devore Imperium inspection teams
     (the Devore are a race with a great disaffection of telepaths, banning them out of their society).
     The patterns of the telepaths were suspended in tanks with contaminated antimatter, which
     blocked the Devore sensors. Unfortunately, the suspension had a nasty side-effect:
     cumulative cellular decay. This means that a person can survive only a few suspensions,
     before dying of cellular decay              "Counterpoint" [VOY]

When Dr. Pulaski is afflicted with rapid aging, the transporter is what cures her. The "science" half of science-
fiction comes into play here; by looking at how the transporter "works" (taking a molecular profile of an individual
and passing it through a transporter buffer) and applying that to a medical problem (using the transporter to restore
Pulaski to her last-known "saved" version), it brings up all kinds of questions.

Transporter weapons: remote detonator: (checks) "Darkness and Light"

In Star Trek IV: The Voyage Home, Dr. Gillian Taylor jumps into Kirk's transporter beam during dematerialization, and rematerializes without any apparent ill effects.

People tend to face an appropriate direction when they rematerialize, although in "Manhunt" Lwaxana Troi rematerializes facing the back of the transporter platform. people who are sitting end when beamed out end up standing when beamed in "Tomorrow is Yesterday" [TOS]
Something similar happened in "Bloodlines" [TNG]  when Picard's "son" was beamed off a cliff face and ended up standing on the transporter pad. This implies that either the transporter can rearrange the various components of your body, which implies that it has a deep knowledge of biology (and this isn't supported), or that whilst in transport, some sort of force field "nudges" the transportee into an appropriate body position.
Also there is no canon explanation for how people maintain their footing when transporting from the evenly surfaced transporter platform to an uneven surface.  But if you beam from the smooth transporter pad to bumpy "Planet Hell", the surface you feel under your feet while in transport could distort; and so you will have time to adjust your balance before you materialize.

According to the TNG Technical Manual, the transporter cannot move antimatter, but this rule has been broken a few times. Such as in the Voyager episode "Dark Frontier", when Voyager transported a live photon torpedo (which contains antimatter) onto a Borg ship.
The animated series episode "One of Our Planets is Missing" has the Enterprise beaming a chunk of antimatter into a stasis box.

Unusual Operating Conditions:

Connecting two transporters

When necessary transporters could be bridged, Federation vessels could activate other Federation vessels' transporters remotely. This meant that two transporters could be connected to each other in the event beaming was not possible due to ionic or some other type of interference.The transport duration was twice as long and the sequence differed from a normal transport. First a remote link to the other transporter had to be established, then the system interlock needed to be engaged and the pattern buffers of both transporters were synchronized. When the phase transition coils were in stand-by mode energizing could commence.  A side-effect of this form of transport might be that the person who was beamed might feel a slight tingling due to static. (TNG|Realm of Fear)

Lock Out:
A transporter could be programmed to only allow one particular person to be transported to and from the transporter pad. Thus programmed, no other persons could use the transporter. If the use of the transporter was further prohibited, by use of an unknown access code, using the transporter was almost impossible.
The only way to circumvent this lock-out was to use the transporter trace from the person who re-programmed the transporter and to input this into the transporter while it was in its testing mode. When in testing mode, a transporter would accept simulated inputs.  When the main computer could not be used, several tricorders could be networked together to control the transporter. To circumvent the lock-out, access codes from a few bridge officers were necessary to force it in a recall loop. So, everyone who would beam down would be seen by the transporter as the person who re-programmed it in the first place. (TNG|Brothers)

Near-Warp Transport - Term used to describe use of the transporter at relativistic speeds (near to
 the speed of light).  A somewhat disconcerting experience to those being transported.
 The Enterprise-D used this technique to transport an away team to Gravesworld while
 en route to an emergency rendezvous with the U.S.S. Constantinople.
                                                             "The Schizoid Man" [TNG]

Emergency mass beaming
Some transporters can transport large numbers of people, and either rematerialize them simultaneously, or in groups. However, this is not often done due to safety reasons. In 2268, the crew of the USSEnterprise NCC-1701 used their transporters in this manner to capture members of the crew of a Klingon ship. In 2377, the USS Voyager transported over two hundred Klingons off a battle cruiser by expanding the transporter's buffer capacity. (TOS|Day of the Dove; VOY|Prophecy)

Transporter Limitations & Interference:
Here is a compilation of things known to interfere with the Transport operation -
[ Time ][ Warp speeds and Above ][ Range ][ Substances ][ Radiation ][ Shields ]
[ Devices / Scramblers ]

Time / Pattern Degradation:Edit  href=
Although beaming was quick, it had its limits. A person could not stay within the matter stream too long.
    If this happened, his or her molecular pattern would degrade and the transporter signal would be lost.

This signal had to stay above fifty percent to be able to re-materialize the person. A time-frame of
    around ninety seconds was about the maximum before that fifty percent signal loss was reached.
                                                             "Realm of Fear"[TNG]
The episode "Realm of Fear" specifies the length of a transport under unusual circumstances would last "... four or five seconds; about twice the normal time". This calculates the length of a typical transport as between 2 and 2.5 seconds and possibly less.

The crew of USS Voyager was able to extend this time by using pattern enhancers. In an effort to
    transport refugee telepaths to another world, Captain Janeway was able to hide many telepaths, in
    addition to a few of her crew, in the transporter buffers. This process was referred to as transporter
However, this process produced serious complications. Because Voyager's guests and crew had to hide
    from Devore authorities repeatedly over the course of several weeks, acute cellular degradation was
    found in many of the refugees and in Tuvok.
Although The Doctor was able to treat them, the degradation was cumulative. If the process was continued,
    the person may not survive the transport.

The longest recorded instance of a person remaining in transporter suspension was that of Captain
    Montgomery Scott, who was also able to survive for a period of 75 years while suspended in an
    extensively modified transporter buffer and setting it to loop diagnostic mode. (TNG: "Relics")

The pattern is probably highly complex. Pattern degradation occurs because the Annular Confinement Beams aren't perfect, even with the help of the Heisenberg Compensators. The matter stream comes out of alignment with the computer's pattern predictions for where things should be. Obviously, this is a bad thing.

According to the TNG Tech Manual, a subject can be suspended in transport for up to 420 seconds before the degradation is too severe to attempt to reform the transportee. They push close to this limit in "Realm of Fear".

In "Relics" [TNG], we see that by keeping the transport controller locked in a diagnostic loop, pattern degradation is kept to a minimum - even with an old-style transporter, only 0.003% of the pattern was lost after 75 years in stasis.

In "Realm of Fear" [TNG], the most extraordinary development is the reconstruction of the lost crew, and their appearance as the giant slugs while in transport. I suspect that the phased-matter "bugs" which reside in the plasma environment act as a natural ACB, maintaining the pattern of those "lost" in transport. The computer is able to use the Biofilter to rebuild the patterns and restore the individuals.

Warp speedEdit  href=

Transporters were not allowed to be used while a ship was at warp speed because of the severe spatial distortions caused by its warp field. (TNG: "The Schizoid Man") Transport at warp was highly dangerous and had been attempted safely only a handful of times. (TNG: "The Best of Both Worlds", "The Emissary")
There were, however, ways to circumvent this limitation.

"Near-warp" transport was possible, but required extensive adjustments to the transport procedure. It involved the transporting ship energizing its transporters at the same time as it dropped out of warp for just long enough for the matter stream to be transmitted. The ship would then immediately jump back into warp.
Persons who had experienced this form of transport remarked that there was a sensation of being merged with an inanimate object briefly before the transporter beam reassembled them.  Near-warp transport has also been referred to as "touch-and-go downwarping". (TNG: "The Schizoid Man")
Faster-than-warp speeds

In 2374, Voyager personnel successfully used Intrepid-class transporters to beam stranded crewmembers from the USS Dauntless while both ships were traveling within a quantum slipstream. Voyager accelerated on a pursuit course during the transport, bypassing the velocity limitations imposed by warp field dynamics. (VOY: "Hope and Fear")

RangeEdit  href=

During the 22nd century, standard Earth transporter systems had a range of 10,000 kilometers; however, by the 24th century, standard transporter systems maximum range was about 40,000 kilometers, though a special type of transport, called subspace transport could beam over several light years. (ENT: "Rajiin"; TNG: "A Matter Of Honor", "Bloodlines") Many 24th century starships were equipped with an emergency transporter system, but these only had a range of at best ten kilometers. (VOY: "Future's End")

Although having a maximum range of about 40,000 kilometers, some conditions adversely affect the effective range. In at least one instance – due to missing components of Voyager's primary computer systems, – the starship Voyager had to be within 500 kilometers of a planet's surface to use transporters on Kathryn Janeway and the hologram character Leonardo da Vinci. (VOY: "Concerning Flight")

The maximum range of a transporter differs per species, depending on what kind of technologies they've used to build it. The transporter with the longest known range is that of the Sikarians, with a range of about 40,000 light years; however this was due to their planet's large quartz mantle which amplified their transporter signal. Because of this, Sikarian transporter technology works only on their planet. (VOY: "Prime Factors")

Gary Seven's mysterious sponsors possessed transporter technology with a range of at least a thousand light years according to Spock. Scotty later noted that Seven's beam was so powerful it fused all of recording circuits, and therefore he could not say exactly how far it transported Seven, or even whether it transported him through time. Exactly how they achieved this effect remains unknown, since there has been no subsequent contact with them, and they hide their entire homeworld in some fashion. There were, however, other indications that their technology was considerably advanced beyond that of the 23rd century Federation. (TOS: "Assignment: Earth")

Dominion transporter technology, enhanced with a homing transponder, was said to have a range of at least three light years. (DS9: "Covenant")

In general, transporters could not be used while the deflector shield of a ship was active, or a deflector shield was in place over the destination. However, it was possible to take advantage of EM "windows" that were created by the normal rotation of shield frequencies. During these periods, a hole opened through which a transporter beam could pass. To use this window, timing needed to be absolute and usually required substantial computer assistance. This technique was theorized and first practiced in 2367 by USS Enterprise-D transporter chief Miles O'Brien. (TNG|The Wounded)

Magnetic shields could also be used to prevent beaming. Rura Penthe was protected by such a shield to prevent prisoners from escaping. (Star Trek VI: The Undiscovered Country)

There was a type of shielding that allowed transport, although it had the limitation of not allowing phasers to be fired through it. (TOS|The Return of the Archons)

The limitation of transporters versus shields was not universal, however. The Aldeans were able to pass through their own shielding using transporters, though the shielding was impenetrable to other forms of technology and weapons. Similarly, both the Borg and Dominion used transporter technology that was able to penetrate standard Federation shielding. Some adaptations, including rotating shield frequencies, could inhibit this ability but not eliminate it altogether. (TNG|Q Who; DS9|The Jem'Hadar)

Transport through shields -
there are instances of this "rule" being broken through a technobabble solution (TNG: "The Wounded")
disregarded by the show's writers (Voy: "Caretaker", Star Trek: First Contact).

Beaming with shields up It is an important concept, that beaming is only possible when the shields are down. Entering the shield bubble with a shuttle isn't possible either, as we learned in "Star Trek V".
In some episodes like TNG: "The Wounded" and TNG: "Relics", however, the transporter is definitely used while the shields are in place.
In "The Wounded", O'Brien used a scan "window" in the shields of the U.S.S. Phoenix to beam over to the ship.
In "Relics" we may assume that Scotty and Geordi, who were on the Jenolan to keep the door to the Dyson sphere open with the ship's shields, transmitted the shield frequency to the Enterprise. On the Enterprise, the frequency of the transporter carrier wave could be matched to that of the Jenolan shields. In a similar fashion the Duras sisters managed to penetrate the shields of the Enterprise-D in "Star Trek: Generations", after they had seen the frequency through Geordi's modified VISOR. It seems that, under normal circumstances without knowledge of the shield parameters, only friendly transporter activities are possible, if any. Otherwise enemies would succeed in beaming over boarding parties more often during a battle.
But in DS9: "The Way of the Warrior", for instance, the Klingons can use only a short time during which the shields of the station are explicitly failing in certain areas.

Cloaking Devices:

in Star Trek III: The Search For Spock, Klingons transport while their Bird of Prey is cloaked, yet in "The Search, Part 1" [DS9] the Defiant has to decloak to transport.

the differences between the Klingon and Romulan cloaking devices may be responsible for the discrepancy; the Defiant cloak is on loan from the Romulans in return for information about the Gamma Quadrant.

in "The Die Is Cast" [DS9] a Romulan ship decloaks on top of a runabout before it can beam the occupants aboard. But in "The Way of the Warrior" [DS9] an entire fleet of Klingon ships stays cloaked until the battle warms up.

One more point - the Klingon clunker in Generations had to decloak before it could beam Soran aboard, didn't it ? We never really were told why nor do we have much to conjecture from, but this is indeed an exception to the rule.

Inhibitors prevent a transporter beam from "locking on" to whatever the device is attached.

Transporter Scramblers distort the pattern that is in transit, literally scrambling the atoms upon rematerialization, resulting in the destruction of inanimate objects and killing living beings by perverting them into masses of random tissue; this was gruesomely demonstrated in the DS9 episode "The Darkness and the Light".
Transporter Scramblers are electronic countermeasures that prohibit transporter activity in a given area. There are no known ways to overcome the scrambler, except through sabotage. Small scramblers can protect a few rooms of a ship or station, while larger arrays can block an entire planet. They are a standard part of Klingon ground assaults and are used in the protection of certain spaces of DS9."Nor the Battle to the Strong" [DS9] & "The Darkness and the Light" [DS9]

Remat Detonators are a Romulan weapon, probably invented by the Tal Shiar, that destroys a transporter pattern during rematerialization. They are very small, only 2 cubic millimeters, and are hidden on the person of the victim. Remat detonators are currently available on the black market as assassination weapons. They are also undetectable to most scans."The Darkness and the Light" [DS9]

Transporter Malfunctions & Damage:

 and Katherine Pulaski express a reluctance to use the transporter.
    "Encounter at Farpoint" [TNG], "Unnatural Selection" [TNG].
Additionally, Reginald Barclay expresses his outright fear of transporting.  "Realm of Fear" [TNG].

Transporter psychosis - Rare medical disorder caused by a breakdown of neurochemical molecules
    during transport.  Transporter psychosis was first diagnosed in 2209 by researchers on planet
    Delinia II.  The condition affected the body's motor functions, as well as autonomic systems
    and higher brain functions.  Victims were found to suffer from paranoid delusions, multi-infarct
    dementia, tactile and visual hallucinations, and psychogenic hysteria.  Peripheral symptoms
    included sleeplessness, accelerated heart rate, myopia, muscular spasms, and dehydration.
    The problem was eliminated around 2319 with the development of the multiplex pattern
    buffer.  Lieutenant Reginald Barclay, suffering from acute fear of transporting, believed he
    might have been suffering from transporter psychosis.
                                                                          "Realm of Fear" [TNG]
Integration of environmental elements into the subject's body:
    Reed beams up Novakovich from the midst of a windstorm.  He reports "contaminants in the matter stream"
    that the "phase discriminator can't isolate".  Novakovich materializes with leaves and leaf-sized pebble-shaped
    things embedded in his skin.                           "Strange New World" [ENT]

The transporter split Captain Kirk into two parts, the accident allowed for exploration of two elements
    of the human psyche. The passive, "good" side of Kirk must subdue and reintegrate with the
    aggressive or "evil" side of himself.
                                                                "The Enemy Within" [TOS]

Will Riker and Thomas Riker are split into two duplicates.
                                                                "Second Chances" [TNG]

To duplicate a living being, a hypothetical effect, which I call an Annular Confinement Beam-Splitter, would be needed. As the ACB was passed through it, along with a supply of raw phased matter, it would duplicate the ACB's contents in the raw stream.

"Hey! What about "The Enemy Within" and "Second Chances" ?"

For better or worse, no such device has been intentionally created by 24th century science. However, in "The Enemy Within" [TOS], Kirk's duplication may have been caused by some accidental effect which caused an ACBS to form in the normal transporter mechanism, with disastrous results. The Encyclopedia says that damage to the the transporter's ionizer was the cause of the split.

In "Second Chances" [TNG], the mechanism by which Riker is duplicated is explained in detail. During transport through severe atmospheric interference, the transporter chief locked onto Riker's signal with a second ACB. When it turned out not to be needed, the second signal was abandoned. The atmospheric interference caused the second ACB to be reflected back to the planet, and somehow the matter stream was duplicated, using phased matter from the atmospheric interference effect to provide the duplicate mass.

"Rascals" [TNG] - Picard, Keiko, Guinan and Ro are turned into children in a freak transporter accident, and later restored. I won't even try. First off, the biology used in this episode is pure BS. Secondly, if a quick fix like this can alter the aging process, then by doing it intentionally, no-one will ever grow old and die again. Amusing episode, but it gets a thumbs down in the Treknology category.

"Unnatural Selection" [TNG] - The transporter magically rejuvenates Pulaski. While the mechanism by which her cure works is relatively sound, the fact that she recovers instantly is anomalous. (See "Man of The People" [TNG] for a similar insta-heal.) Better to just not ask.

"Tomorrow Is Yesterday" [TOS] - Somehow, the transporter is able to erase the memories of people by transporting a newer version of themselves over top of an older version. Talk about saving the day by transporter abuse!

"The Enemy Within" [TOS] - While I can buy the duplication effect, and maybe even the two disparate personas of the two Kirks, I think the recombination of the two was pushing the technology a little bit.

Mirror Universe:
In 2267, an ion storm caused a transporter accident. After failing to persuade the Halkan Council to allow the Federation to mine dilithium in on their planet, a USS Enterprise landing party, expecting to beam back on to their ship, were beamed aboard the unfamiliar ISS Enterprise NCC-1701 in the Mirror Universe.  Upon beaming aboard, they discovered that the peace-loving United Federation of Planets had been replaced with a brutal Terran Empire, and that they had their own "mirror" counterparts.  During an ion storm, the transporter became a gateway to a parallel universe, where the Federation is an Empire.  It transported our people there and their people here.                                                                "Mirror, Mirror" [TOS]

"What is Phasing?

Star Trek seems to have this notion of "phased" as a state or quality of matter and energy. Things can be offset slightly in a time-like dimension from our "phase" of the universe. The idea being that if you and I have different "phases" we can't interact with each other without using special particles or fields or the usual [TECH].

This is borne out in "The Mind's Eye" [TNG], where Geordi lists the five states in Sub-Quantum Transformational Relativity:

Phasers set on kill appear to work by violently phasing their target into one (or more) different phases. Ouch. This explains rather nicely why they just disappear and don't go "boom". Chronotons, which have been linked to time travel and associated effects, are also mentioned with regards to phasing a few times.

"The Tholian Web" [TOS] - The U.S.S. Defiant and Captain Kirk get trapped in an "interphase" rift, phasing in and out.

"The Next Phase" [TNG] - Geordi and Ro and a Romulan get accidentally phase-cloaked within the Enterprise. They can walk through walls and people. (They don't fall through the floor, though.) A high-intensity sweep with anyons return Geordi and Ro to normal phase.

"Time's Arrow" [TNG] - Phased creatures from Devidia Two are travelling through a portal to 19th Century Earth to steal neural energy. A subspace field can be used to align the phases of the Enterprise crew and the creatures.

"The Pegasus" [TNG] - The Enterprise uses a phase-cloak developed illegally many years ago by the Federation earlier to escape from an asteroid. The cloaking device phases the entire ship.

"Relics" [TNG] - Scotty couples the transporter phase inducers to the pattern buffer to create the suspension effect. Given that transporting involves conversion to a beam of matter and energy, and that you can transport through walls, that beam better be phased or there'll be some big nasty holes whenever people transport.

Nyrian Translocator -
    The Nyrians used this transportation device to transport the Voyager crew to the compound and
    replace them on Voyager with Nyrians; it has a range of 10 light years; its long range limits its
    capacity and it may only be used to send one person at a time;  Janeway and Tuvok take control
    of the translocator system and transport Dammar and Rislan to the Argala compound; Janeway
    says that after they will disable the translocator and contact the native worlds of the other prisoners,
    the Nyrians will be free to go.          "Displaced" [VOY]

Rutian Inverter -
    A device used by the Ansata terrorists of planet Rutia IV for folded-space transport.  Using the
    inverter, the Ansata were able to transport interdimensionally, without being detected by Rutian sensors.
    The device, used by the Ansata in 2366, brought new life to the Ansata cause, despite the fact that
    repeated use of the inverter caused cumulative, and eventually fatal, damage to the user's DNA.  Because
    the use of the device caused subspace pressure modulations, Commanders Data and La Forge and
    Ensign Wesley Crusher were able to locate the power source of the device with adaptive subspace echograms.

Sikarian Trajector matrix -
    Transporter device used by the Sikarians, Its maximum range is 40,000 lightyears, giving the
    opportunity for Voyager to get closer to home. However, the Sikarians didn't want to share the
    technology.  The trajector uses the principle of space folding (folding the space-time continuum
    to make two places closer together), a technique that the Federation never has developed.
    (SEE: Elway theorem)  The concept was abandoned in the mid-23rd century.  The folding
    mechanism is not well known, but we do know that the neutrino field it generated was 10 times
    bigger than any force- or particle field ever generated in Federation history.  To create a field this
    large, an amplifier the size of an entire planet is needed. The Sikarian planet's mantle of crystallized
    quartz is used as an amplifier, making the trajector only usable near the Sikarian homeworld.
    Janeway wants to exchange Voyager's stories for this technology of the Sikarians; Torres
    discovers that it is not compatible with federation technology because of the anti-neutrinos
     it generates.    "Prime Factors" [VOY]
