| | An electromagnetic pulse generator (EMP) is an anti-electronics weapon that mimics the intense EM radiation emitted by a nuclear explosion. The resulting EM field couples with nearby electronics systems, producing massive, damaging electrical currents. An old EMP device was being transported to Caprica from the Galactica on [[Colonial Heavy 798]] (later [[Colonial One]]), presumably to place in a planetside museum or school as a historical artifact ([[Mini-Series]]). As the destruction of the ship by a Cylon raid seems imminent, [[Lee Adama]] activates the weapon, giving the appearance that the Colonial One had been destroyed by a nuclear blast. This attempt appears to be successful, as the Cylons cut off the assault and Galactica's radar confirms the ship as destroyed. The Colonial One's electronic systems seem to be fully functional, however (The actual science behind this particular EMP is never actually explained, much like the mysterious artifical gravity). |

| An electromagnetic pulse ('''EMP''') generator is an anti-electronics weapon that mimics the intense EM radiation created by a nuclear explosion in an atmosphere. The resulting EM field couples with nearby electronics systems, inducing electrical currents and voltages, thus damaging sensitive electronic equipment. | |
| | |
| Pulse generators are able to act independently, at some level, without needing to be connected to a ship's power grid. They may be an offshoot of, or connected to, [[FTL]] technology due to its employment of hyperspace principles {{TRS|Miniseries, Night 2}}.

| == Practical Use ==
| |
| Just before the [[Fall of the Twelve Colonies|Cylon attack]], electric pulse generators are being transported to [[Caprica (RDM)|Caprica]] from the decommissioned [[Galactica type battlestar|battlestar]] ''{{RDM|Galactica}}'' on ''[[Colonial Heavy 798]]'' for a purpose unknown to {{callsign|Apollo}} {{TRS|Miniseries, Night 1}}.
| |
| | |
| As the destruction of the ship by [[Cylons (RDM)|Cylon]] nuclear missiles is imminent, Lee Adama activates the devices, giving the appearance that ''Colonial One'' had been destroyed by a nuclear blast. This ruse is successful, as the Cylons do not immediately return. The missiles were disabled by the EMP with an energy pulse so strong that ''Galactica''{{'|s}} [[DRADIS]] picks up the pulse, which leaves [[William Adama]] grieving for the apparent loss of his last son {{TRS|Miniseries, Night 2}}. | |
| | |
| The human passengers are stunned unconscious by the pulse as well, but soon recover.<ref>The [[Miniseries]] shows the EMP temporarily overloading the crew's central nervous system and causing unconsciousness. However, this is scientifically incorrect, because although the human nervous system works with electrical currents, there is no metal to act as antenna for the magnetic field and induce a damaging current. The effects shown are either a writing error, or the result of some other force.</ref> ''Colonial One's'' electronic systems seemed to be fully functional after the attack.

| ==Notes==
| |
| | |
| *[[File:TRS - Miniseries - Haphazard Material Handling at Ragnar Anchorage.jpg|thumb|Generators in the background while material handling goes awry on [[Ragnar Anchorage]] {{TRS|Miniseries, Night 2}}.]]These devices are probably standard equipment aboard ships such as battlestars, given Lee Adama's knowledge about the electric pulse generators. The [[Ragnar Anchorage]] also has this equipment available in their inventory, suggesting wider-spread use.
| |
| *Such devices might have been part of a battlestar's fighting tactics against Cylon attacks in the first [[Cylon War]], but [[Humanoid Cylon|not in the second]], since Cylons were [[Cylon Centurion Model 0005|purely mechanical]] at the time and their circuits were vulnerable to EMP attacks unless shielded. Given that a non-military craft such as ''Colonial One'' recovers very shortly after the pulse, the EMP may not be an effective ship-disabling weapon. Lee Adama mentions that simulations performed at [[War College]] resulted in low probabilities that a generated EMP would fool Cylon forces, suggesting that EMP's are a defense and deception tool rather than a weapon {{TRS|Miniseries, Night 2}}.
| |
| *During the [[Fall of the Scorpion Fleet Shipyards]], the battlestar ''[[Pegasus (RDM)|Pegasus]]'' gains valuable time to escape by a [[blind jump]] when the radiation from the Cylons' nuclear weapons temporarily blinded their own DRADIS {{TRS|Pegasus}}. <ref>Admiral [[Helena Cain|Cain]] says "the blast blinded the Cylon DRADIS," making it unclear to which physical phenomenon she refers to exactly. This effect is not an EMP in the strictest sense, since a significant EM field is only created when a nuclear detonation's gamma-ray emissions interact with the matter in an atmosphere and produce free electrons through [[w:Compton scattering|compton scattering]], which in turn interact with a planet's magnetic field. There are no nuclear EMPs in the vacuum of space. The gamma radiation generated by an explosion alone can nonetheless disrupt DRADIS and [[wireless]] communications, as they rely on a form of EM radiation as well. Another possibility is the interaction of the gamma radiation with vented atmosphere or the outer layers of the planet's atmosphere.</ref>
