Ancient technology in Stargate

The Ancients (also known as "Alterans" and "Lanteans") are a fictional advanced race in the Stargate franchise, and are depicted as the precursor to modern-day humans. Their most notable creation in Stargate mythology is the entire Stargate network. Ancient science and technology, with a few exceptions, is shown as being superior to that of other races. The Ancients are portrayed as being extremely advanced in the areas of healing, power generation, and biology. They are also credited with designing a number of fictional weapons, primarily for use in the centuries-long war with the Wraith in the Pegasus Galaxy. Ori technology in Stargate is shown as similar to that of the Ancients, since they are also depicted as ascended beings. In Stargate chronology, all Ancient technology was created prior to their ascension, with the exception of the Velona weapon, assisted by the character Orlin, and the weapon created by the character to destroy ascended beings. However, not all the artifacts credited to the Ancients are depicted as a complete success.
Power sources
Ancient technology has varied in power and capability over the passage of many millions of years. The multi-million-year old vessel Destiny possesses an early hyperdrive system that manages FTL travel in normal space with the use of multiple modular drives. Although much slower in terms of speed than the later hyperdrive systems that utilized hyperspace windows, Destiny possesses the ability to convert plasma discharges from the chromosphere of a sun into energy without damage, giving it the ability to recharge at any point in travel. This unending power supply allowed the Destiny to travel much farther than any other ship, even though their method of FTL was much slower compared to modern hyperdrives.
Zero Point Module
An Ancient power source used to power their cities and outposts. ZPMs supposedly extract vacuum energy from a small artificially-created region of subspace, based on the concept of zero-point energy. ZPMs are depicted as more powerful and efficient than fictional Naquadah generators or any conventional energy source on present day Earth, and are shown as lasting for thousands of years.
The first ZPM is found by Jack O'Neill in the SG-1 season 7 finale "Lost City" at an abandoned outpost, and used to power Ancient weaponry left behind on Earth to repel Anubis' attack on Earth. The same ZPM allows Stargate Command to open a wormhole to Atlantis in the Pegasus Galaxy. the Trust, and McKay aboard an Asuran City ship.
Most of the Atlantis characters and aliens pronounce ZPM as Zee-P-M (with an American accent). The team's Canadian scientist, Rodney McKay, on the other hand, pronounces the abbreviation in the standard Canadian (and all other non-US English speaking territories) fashion, Zed-P-M.
Other power sources
*Project Arcturus: Experimental project to extract vacuum energy from the current universe, which could replace Zero Point Modules, based on Doranda. It failed and several Ancients involved died trying to shut it down. The Atlantis Expedition discovers the device, but run into the same problem: the device constantly generates new and exotic particles that would make it impossible to stabilize, which causes the destruction of 5/6 of the local solar system. The Atlantis team later experiments with shunting the exotic particles to another universe. However, the other universe is inhabited, and an alternate McKay travels to Atlantis to stem the damage being done to his universe.
*Ram scoop like devices: The Ancient starship Destiny is powered by a series of devices similar to ram scoops on each "fin" at the rear of the ship. The vessel flies through the corona of a star to recharge its reactors. The shields protect the vessel from the intense solar heat while this process occurs.
*Submerged Geothermal Station: A small facility the Ancients constructed to find an area where volcanic activity was close to the surface. Once found, the Ancients made use of the planet's geothermal energy. An umbilical cord is tethered from the facility to Atlantis to deliver power.
*Supervolcano Geothermal Facility: A large Ancient outpost was discovered on Taranis, a planet in the Pegasus galaxy where the Orion was also stored. This outpost contained an Ancient shield and utilized geothermal energy from a dormant supervolcano. Excessive use of the facility destabilized the volcano, resulting in an eruption which rendered the planet uninhabitable.
*O'Neill's jury-rigged device: The first time that Colonel Jack O'Neill had the knowledge of the Ancients downloaded into his mind by an Ancient Repository of Knowledge, he used this knowledge to build a complex device that interfaced with the power supply for Earth's Stargate. The device provided the requisite amount of power for the Stargate to create a wormhole to another galaxy by depleting the liquid Naqahdah energy cell of a staff weapon, which allowed O'Neill to travel to an Asgard-controlled location in the Ida galaxy. The device he built to power the Stargate for this purpose worked only once until a second Samantha Carter arrived from a parallel universe, and the two Carters managed to figure it out so that the Alternate-Carter could return to her universe via the Quantum Mirror and contact the Asgard (by travelling to the Asgard's home galaxy via Stargate) to stop the Goa'uld Apophis from conquering Earth, similar to what Daniel Jackson had witnessed when he discovered the Quantum Mirror on an abandoned planet.
Shielding
Shields were used by the Ancients aboard their ships and outposts. Ancient shields prove to be almost impenetrable, as long as sufficient power is maintained to operate them. In contrast, the shields of other races, such as the Goa'uld and Asgard, are weakened directly by outside forces, like enemy fire and natural phenomena, causing them to fail or diminish in capacity rather quickly in cases of extreme stress. Various types of shields include:
*Prison cell shield: Ancient prison cells are known to employ shields between their bars to prevent occupants from escaping, as shown within Atlantis as well as their ships. Atlantis' sister ship was shown not to have this capability but this is most likely due to the severe lack of power available.
*Aurora-class shields: The shield of Aurora class warships contours around the ship, like an extra hull, instead of an ordinary bubble. These shields are incredibly powerful, and have a yellow gold-like color. The Orion's shields, operating at well-below full power, were able to withstand a supervolcano's eruption for 4.1 seconds, while using the eruption to propel it out of its hangar.
*Atlantis' shield: The massive dome-like force field protects the city from enemy attacks, and water pressure when submerged in the ocean. Three personal shields have so far been encountered. One was discovered in Atlantis and used by Rodney McKay, but its power source is depleted by an energy-absorbing creature. The third is used by Lucius Lavin, although its power source was later depleted.
After a completed transport, the rings move back into their storage platform and deactivate. The rings themselves do not transport. Some ring platforms are portable and can be moved when inactive. They have sensors that detect other active transport rings in an area. Transport rings are also used to enter and exit spacecraft, with one set of rings inside the craft and another set of rings mounted outside the hull. This is commonly seen with the Goa'uld Tel'tak cargo ships and Al'kesh, and some of the Earth ships. It is possible to intercept a matter stream that is in transport by interposing a set of mobile rings between the sending rings and the planned receiving rings. However, such an intercept requires that the entire matter stream be captured by the intercepting rings; otherwise, the transported people will not fully reintegrate, resulting in death. In the original Stargate film, O'Neil used the rings to decapitate one of Ra's foot soldiers by pinning him under the rings as they were activated, causing only the soldier's head to be transported.
Stargate
Also known as Astria Porta in Ancient, and to the Goa'uld and Jaffa as the "Chappa'ai" (Cha-Pa-Eye). to control them, forming the Stargate Network. A traveller may use any Stargate to travel almost instantaneously to any other Stargate in the system, so long as he knows the "address," a combination of at least seven symbols (six for the absolute 3D position and one for the point of origin, in order to calculate the relative position) that must be entered on the DHD (and assuming that the traveller is aware of stellar drift and can compensate for its effect on gate travel). Gates with a DHD communicate with each other through updates. The only gate that has to take stellar drift into consideration is Earth's gate since it does not have a DHD. Eight symbols must be used to dial a stargate that is in a different galaxy (the extra symbol referred to in SG-1 as being "like an area code"). The nine-symbol address is a specific combination used to dial the Destiny, a massive Ancient vessel that was part of a project to explore the universe, before the Ancients ascended. A Stargate is a two-way portal in some respects; while it can only be physically entered from the side from which it is activated, data transmissions are duplex, as shown by communications with off-world SG teams. Simultaneous physical access is impossible. The Stargate is often considered to be the Ancients' most famous creation, as the Ancients are often called the "Gate Builders". Because the Goa'uld are scavengers, they claimed that they were the builders to make the populations of the planets they enslaved worship them as gods.
Other
*"Eye of the Gods": A large obelisk located not far from the Stargate of the Sodan world, it transports people to another location where a similar transporter is located to get back. An energy signature is detected within the column of stones, although it remains unknown how the device functions. A control crystal is required to activate the obelisk. Without the crystal, the obelisk can be transported to, but cannot transport people back.
*Atlantis transporters: The cityship in Stargate Atlantis does not appear to be equipped with ring transporters but instead has transporter rooms (initially mistaken for storage cupboards) which would seem to be an upgraded version of the technology as they work in a similar manner. They may also be compatible with ring transporters similar to the way that separate era stargates are compatible.
*Beam transporter: Outposts built by Ancients after their return from the Pegasus Dwarf Galaxy possessed transporters that were similar to Asgard transporters. Such devices were used to reveal treasures to SG-1 after passing several tests.
Weapons
Asurans
The ultimate product of extensive Ancient research into smaller and more effective weapons for use against the Wraith, the result being microscopic nanites capable of attacking and destroying Wraith cells. They were programmed with an aggression that surpassed even that of the Wraith, and the ability to replicate to far greater numbers to increase their effectiveness. They replicated at such a rate that they took even the Ancients by surprise. As they became more advanced, the molecular machines began interlocking and assembling themselves into more complex constructs, and eventually they reached the point where they exactly emulated the Ancients in appearance. They desperately pleaded with the Ancients to have the aggression removed from their base code, but since the Ancients included a directive in the coding that prevented the Asurans from harming them, they continued the experiment. After the Ancients concluded that the Asurans would never become the weapon the Ancients desired to create, the Ancients launched a massive attack on the Asuran homeworld in an attempt to destroy the Asurans, and then erased all traces of the Asurans in the Ancients database. Even after this, a few nanites survived and began replicating, bringing about a second-birth of their kind. It is capable of destroying all life in the galaxy as well. Anubis intended to use it to repopulate the galaxy according to his own designs. However, Jacob Carter recognizes that it is also the galaxy's only hope against the Replicators. The weapon uses an energy wave that decomposes matter into its constituent parts. He (along with Selmak), Samantha Carter, and Ba'al reprogram the device to emit an energy wave matching that of the Replicator Disruptor, and send it through all the Stargates in the galaxy at once, and wipes out the Replicators. In , Anubis conquers Dakara and almost completes his plan to wipe the galaxy clean, but is stopped by Oma Desala. Confronted by how close they came to annihilation, the Free Jaffa Nation agrees to dismantle the device. However, in , the weapon is used again to fight the Ori. The Jaffa High Council uses it to eliminate the crew of an Ori mothership, so they can capture it. Their attack is successful, but the Orici Adria is protected from the weapon by her personal shield, and takes the Ori mothership to Dakara where she fires a weapon that annihilates the Dakara superweapon.
Drone weapon
An extremely powerful projectile weapon, shaped like a meter-long squid, capable of autonomously targeting and destroying its target, even if it is moving extremely fast. These are the Ancient's main type of weapon. In the Pegasus Galaxy, drones are rare in the aftermath of the loss of the Ancients' war against the Wraith. Only a few dozen remained in Atlantis, which were used up during the siege by the Wraith. The Asurans also use drones. In the Milky Way, thousands of drones have been discovered in Ancient outposts such as the Antarctica outpost. and can be controlled either by continuous operator control or in a fire-and-forget manner.
An active drone is enveloped in a bright yellow glow. Drones fired from a control chair require a ZPM for normal operation, and a single drone can seriously damage a Wraith cruiser. Drones have the ability to shield itself from impact with matter to a certain degree, allowing them to literally tunnel through larger enemies such as ships before returning to detonate. Drones have also been observed passing through ships, with unused ones heading back to their launch site,
There is a smaller variant called mini-drones. It is theorized that the drones are used to guard certain areas against people without the ancient gene, as was the case on queen Harmony's planet where only the wearer of a special ancient "key" (pendant) can control the mini-drones from the "test site" where the Ancients developed mini-drone technology, which was perfected in Pegasus while the normal sized drones were invented in the Milky Way.
Mini-Drones
Mini Drones are essentially miniature versions of the Drone Weapons used by the Alterans. They were encountered in the episode "Harmony", when Lieutenant Colonel John Sheppard and Doctor Rodney McKay discovered an Ancient Obelisk that controlled the Mini Drones. The ATA (Ancient Technology Activation) Gene and a special Pendant are required to use the Obelisk and activate the Mini Drones.
Replicator Disruptor
The most effective weapon against Replicators, and the only one completely effective against human-form Replicators, it disrupts communication between cells, rendering each one inert. When fired, any Replicator in its blast radius falls apart into its constituent units. The weapon is created by Jack O'Neill, who had the entire Ancient Database downloaded into his mind at the time, in conjunction with Asgard computers. However, the Replicators are able to become immune to the device, requiring the recalibration of the disruptor. The actual prop was piston-driven and had a trigger device inside. Because the model shop knew that actor Richard Dean Anderson would play with it off-screen, they made it extra-robust. Area 51 produced a version of the Replicator Disruptor specifically to combat the Asurans. (see "").
Sangraal
Also known as the Holy Grail or (as in the episode "Camelot") the Bloodstone, is a weapon designed by to neutralize ascended beings, including the Ori, but cannot target a specific group of ascended but rather wipes all of them out within the weapon's range. The weapon consists of several devices working together, with a red stone as the "key" to make it work. According to Daniel Jackson, the notion of the Grail as a cup or chalice was a late addition to the myth, but some chroniclers originally described the Holy Grail as a stone that fell from the heavens. Exactly how it works is unknown, but the Asgard have surmised that it's an energy transfer device, similar to a Zero Point Module, except that the energy is channelled not from sub-space into ordinary space-time, but rather into the dimension occupied by Ascended beings. The effect of this again theorized by the Asgard as two standing waves canceling each other out, with the result that the Sangraal would essentially 'negate' the Ori. The Sangraal is launched through the Supergate by Dr. Jackson
Lagrangian Point Defense Satellite
Enormous satellites floating in deep space, equipped with an energy beam weapon powerful enough to cut a Wraith Hive-Ship in half. Puddle Jumpers can dock with it. The satellite can be charged by multiple types of power sources, storing power in its capacitor until it has enough energy to fire. During the war with the Wraith, Atlantis was guarded by a network of satellites placed at Lagrangian Points to protect the city. However, they were destroyed one by one, until eventually only one remained, damaged and without power. When the Wraith decide to attack Atlantis again after the Atlantis Expedition had taken up residence there, a team led by Rodney McKay repairs the satellite to use against the incoming Wraith fleet. The repairs allowed the weapon to destroy one Hive-Ship using secondary power lines, but the systems overloaded after the first shot and it is soon destroyed by a barrage of Wraith weapons fire.<span id="Attero_Device"></span>
*Attero device: An extremely powerful weapon built by Janus, which emits subspace interference to destabilize the region of hyperspace used by the Wraith. As a result, any ship using a Wraith hyperdrive is destroyed upon entering hyperspace. It was abandoned by Janus because it emits radiation which causes energy to quickly buildup within any active Stargate in Pegasus, leading to its destruction in a powerful explosion equivalent to twelve nuclear bombs. The device is reactivated by a renegade Asgard faction unconcerned with the loss of lives, but is eventually shut down by Dr. McKay, then destroyed by a Travellers ship, so it cannot be used again. The control key, however, is taken by the Asgard.
*Explosive tumor machine: An extremely powerful bio-weapon created by the Ancients. The device emits radiation which causes the body to gather specific elements in a tumor behind the victim's lung, which eventually explodes. The device is activated by two scientists in Atlantis, one of whom dies. The other is saved by Carson Beckett, though Beckett himself is killed when the excised tumor explodes.
*Gate overloader: A weapon able to target a Stargate and turn its naquadah to a deadly weapon. The weapon would send massive amounts of energy through a Stargate to be stored in the receiving gate, which would keep absorbing energy until it can't hold any more, eventually exploding with devastating power. The resulting blast would be big enough to destroy Colorado, and the ensuing dust cloud would destroy all life on Earth. It is capable of maintaining an active wormhole between two Stargates indefinitely, until the target gate is destroyed. It is used against the Tau'ri by Anubis, although the SGC is able to dispose of the gate, transporting it to space before it explodes. The weapon itself is destroyed by Teal'c, Bra'tac and Rya'c.
Miscellaneous technologies
Shrine of Talus
A device with an unknown purpose, which is powered by a super heavy element giving off an unknown form of ionizing radiation. A parasite that causes "Second Childhood" is affected by the radiation, allowing those suffering from the ailment to become themselves for a day before a quick death from immune system failure or leaving the range of the shrine's radiation.
ATA Gene
The Ancient Technology Activation gene (ATA) is a specific gene present in all Ancients, and some of their human descendants, which acts as a key to much of their technology; if the user does not possess the gene, the technology will not activate. The ATA gene instructs various cells in the body to produce a series of proteins and enzymes that interact with the skin, nervous system, and brain, allowing the gene carriers to operate Ancient technology. Though rare naturally in most humans, Dr. Carson Beckett develops a retroviral gene therapy (using a deactivated mouse retrovirus) to transfer the Ancient gene expression to humans, The necessity of the gene in utilizing Ancient technology varies. In some cases, like use of the Control Chair, the gene is required for continued use, while other devices simply need to be initially activated by someone with the gene, after which anyone can use the device. Gene expression is stronger in some carriers, allowing them to use Ancient technology instinctively while others require training and practice.
Natural gene carriers from Earth include Major General Jack O'Neill, Dr. Kusanagi (who was mentioned but never seen), and Joe Spencer. Gene carriers by therapy include Dr. Rodney McKay (as the first human trial), Colonel , and some of his troops. Gene carriers of unknown source include Lieutenant Miller, Dr. Abrams, and Major Lorne. The gene therapy did not work on Dr. Radek Zelenka. suggesting that Daniel may also be able to use Ancient technology as he was an ascended being. Whether his ascension or the repository were responsible for his ability to use Ancient technology at the time is unknown, as he has not used any ATA gene-based technology since. Lt. Aiden Ford asked for the gene therapy during the nanovirus crisis, series' writer Martin Gero explained in an online message that he does not have the gene, because "The Jumpers, while near and inside Atlantis, are pretty much on autopilot when it comes to landing and taking off."
Series writer and producer Joseph Mallozzi has stated in his blog that the ATA gene did not factor into any Stargate Universe story lines.
==="Arthur's Mantle"===
A device built by Merlin that pushes matter with normal reality, making everything within its area of effect invisible and intangible. It also doubles as a computer. The device was used to conceal his research on the Sangraal, a weapon capable of destroying ascended beings. The console was concealed in the Avalon cave under Glastonbury Tor, England. The device was named by Merlin's trusted aides, the Knights of the Round Table. In order to access the data from its computer, the user must be out of phase, to prevent the ascended Ancients from discovering it. The device itself is accessible from either dimension, allowing a person to enter and exit. Although being out of phase hides the user from both the Ancients and conventional observers, those wearing Sodan personal cloaking device, which operate on a similar principle, can observe affected matter, though they cannot interact with it. The device is accidentally accessed by Colonels Carter and Mitchell, who were rendered out of phase by the device. With the eventual help of Daniel Jackson, they manage to return to normal; however, its power source is permanently depleted in the process. The device is then exploited as a defensive weapon by Colonel Carter, first on a village under threat by the Ori then on the entire planet Earth in an alternate reality.
Communication device with stones
A dome-shaped device with a blue crystal spire designed to facilitate communications across vast distances. The device works in tandem with palm-sized oval stones. When inserted into one of twelve slots on the base, the stones allow the user's mind to take over the body of whoever last touched the stones on the other end, provided someone with the ATA gene activated them.
One of these devices was discovered under Glastonbury Tor, and it was subsequently used by Dr. Jackson and Vala. It transported their minds to the Ori galaxy into the bodies of a married couple, Harrid and Sallis. Several months later, Vala Mal Doran contacted the SGC from the Ori Galaxy using the device thanks to the Ori underground resistance, and warned SG-1 about the nearing Ori invasion of the Milky Way. However, the link was cut by her husband Tomin. Another communication device was found in the Pegasus galaxy, switching Dr. Keller's mind with that of a thief. Both Keller and the thief were able to use each other's bodies despite the lack of a second device. Unable to find any shut-down switch, Ronon shoots it to break the link.
In Stargate Universe, Stargate Command has apparently devised a more compact version of the communication device. This version is a boxed-shaped device with room for five stones in an 'X' formation. The stones are simply placed on the flat panel of the device to activate it. It can be deactivated by removing the power source attached to the base. The team aboard the Destiny has access to one, as does Stargate Command, allowing for regular communication between the expedition and Earth. Like the original, the transfer works both ways and will only deactivate when deprived of power (which is much easier with this version). Due to the vast distance between Earth and the Destiny the transfer will only work if both devices are active, and deactivating either device will terminate the link. In addition, stones must be placed on both devices for a transfer to occur, as shown when Young had to bring in an additional person to switch with Chloe after they both used the device (Telford had been the only one present on the other end). However, connections across a shorter distance (as in the same or adjacent galaxies) still work with only one device present, as seen when Young switched body with a Blueberry Alien. These Aliens seem to have developed a similar device, however Col. Young later discovers that Dr. Rush was secretly keeping a stone with him for personal use, which they found and used to switch bodies with Vanessa James. This issue was compounded when she did not have her imprint erased from the stone she was inadvertently switched with a member of the alien race who ended up sabotaging Destiny.
The SGU device has been shown to glitch when Destiny jumps to FTL travel, allowing for minds to be inadvertently returned to their host bodies.
The SGU device's link is also terminated upon either linked individual entering an active Stargate, or at least one going to Destiny.
It is also revealed that the death of one person using the stones, also kills the person on the other end. (As an edit, a more current episode shows that the physical body of the person dies while the mental being of the person gets lost and "floats" around.) The mental part was able to be reconnected with by the stone user to fall asleep. The person(s) mind(s) would then download into the stone users and will disappear and be lost if it is not taken out of the body i.e. through a neural link in a control chair. In SGU one of the characters has two other characters minds downloaded into her brain through the stones (who were thought to be dead) and were taken out through the chair on board.
Control Chair
A chair-shaped neural interface which allows the user to remotely control systems on whatever facility the chair is installed in, such as the Ancient City Ship or smaller Ancient outposts like the one in Antarctica. The chairs, like most Ancient technology, requires the Ancient Technology Activation gene. They are primarily used to fire and control Drone Weapons, though they are also shown to be used to pilot spacecraft in addition to more minor systems such as holographic projectors and power distribution. In the Pegasus Galaxy, chairs are located in the tower of Atlantis
The device works by altering a subject's DNA and consequently increasing their brain activity from roughly 10 up to 90 percent (based on the popular but inaccurate myth that humans only use 10 percent of their brain at any given time). perfect memory, and the power to heal by touch. It was confirmed in Season 9 of SG-1, Later, in the editing process, the third component was added: a computer-generated energy field which appears to paralyze the user, and a computer-generated representation of DNA surrounding the user.
A device with similar capabilities was found in an initially submerged part of Atlantis, although it differs considerably in appearance. The disposition of the command console on a pedestal and under the blue light emitter of the "resequencing" field suggest it was designed for self-modifications.
Holographic sentry
A hologram was used as a security measure by Merlin in his vault in "Avalon" and at his library in "Camelot". The hologram was capable of interacting with people and certain other projected objects, particularly holographic swords, but bullets would pass straight through it when fired at it. The hologram was designed to resemble a medieval knight, to test the worthiness of those who entered. If the program had determined the visitors to be "worthy", the treasures and hidden technology inside the cave would be revealed. When SG-1 gained access to the cavern, the sentry was eventually defeated by Cameron Mitchell.
Repository of Knowledge
The Repository of the Ancients is a device that stores all knowledge of the Ancients. The interface is a metallic circle, with a dark window in the middle, and is usually attached to a wall. The console is designed to allow a human to place his/her head into it, whereupon the device grabs them by the temples and downloads the entire database into their mind. The transfer of knowledge from this device can cause serious problems for beings whose physiology is not prepared to take the mental strain. The device was used on two separate occasions by Jack O'Neill, both times threatening his life; during both of these times, he was able to build a powerful generator. He was also shown to be able to create a weapon capable of defeating any Replicators and use healing powers. A variation appears in "The Quest". This version is smaller, does not latch on to the user's head, and has additional, hand-sized input devices at its base. It interfaces with a replication device to allow users to build devices from the molecule up. It was used by Merlin to create the first Sangraal. Merlin downloaded his mind into the device when he could not complete work on the second, allowing Daniel to finish it. It also allowed Daniel to use telekinetic powers.
In Stargate Universe series, the spaceship Destiny has a primitive version of the control chair, which also acts as the ship's repository of knowledge.
Stasis Chamber
A device designed to put the occupant into a state of suspended animation. The device slows the user's bodily functions to a near halt but does not stop them. Thus, over long periods, the person can potentially age to a point where being removed would be fatal. One such device was located inside the Antarctic outpost and used by Colonel O'Neill, who put himself in stasis to stop the Ancient knowledge in his brain from killing him. Another such device is found containing Merlin himself, who stayed in suspended animation for about 1,000 years (since the time of King Arthur), when SG-1 enlists his help to re-create the Sangraal. A second form was later seen in the Milky Way, used by Morgan le Fay as one of her tests for persons searching for the Sangraal. This model had a set field around the location of the mountain, which almost froze objects that entered the field and was the reason why many human villagers were lost on the quest as they had become trapped in the field. However, as part of the test, a set path is present that allowed movement without being compromised.
Other
*"": An Ancient device used to measure a person's synaptic activity. Designed to work alongside the DNA Resequencer, the scanner analyzes a subject's current physiological status and feeds the information back into the resequencer. It was able to locate the areas of the brain that were used for advanced abilities such as telekinesis, and was apparently used by the Ancients during their pursuit of Ascension. One of the scanners was discovered in the lab where Anubis created and experimented on Khalek, a clone created by Anubis using his pre-ascension DNA. After the SGC brought Khalek back to Earth for study, the scanner was brought with them and used to monitor his development. The device was nicknamed "ascendometer" by Colonel Mitchell.
*Kino: A spherical data-gathering device about the size of a softball found aboard the Destiny in Stargate Universe. It has audio and visual recording abilities, as well as a wide range of other scanning devices. It hovers under its own power. The Destiny apparently carries a large supply, dispensed from a device resembling a gumball machine. The devices can be controlled by a primary panel near the dispenser or through handheld remotes. It is the Ancient equivalent of a MALP, as it can be sent through an active Stargate and controlled remotely to gather data about the planet. Eli Wallace discovered the Kinos and named them after the Russian Kino-Pravda newsreel series. Eli uses the room housing the device as his personal quarters.
*Magnetic harmonic resonance: A device created by Janus in order to hide a secret laboratory on Atlantis and discovered by Rodney McKay and Daniel Jackson. The device is activated by emitting a series of tones tuned to a specific resonance frequency which destabilizes the atomic structure of an object. Magnetic fields are used to preserve the shape of the object, and to prevent material making up the object from getting swept along with other objects passing through it. The only known example of this technology has been to create a wall hiding the entrance to Janus's lab.
*Personal cloaking device: Consists of a triangular crystal worn around the arm,<ref name="Babylon" /> allowing a user to exist out of phase. They can still see and interact with each other. Apparently, the cloaking device works similar to the Ancient device known as "Arthur's Mantle", as the cloak's user will be able to interact with someone rendered out of phase by the Mantle, though they would still pass right through them if touched.<ref name="Arthur's Mantle" /> The devices were mostly used by the Sodan, though the SGC acquired several after the Sodan were exterminated by the Ori. Schematics for an Ancient cloaking device were found in Janus's secret lab, suggesting he may be the one who designed the device.
