Phase Pulse Generator

The Phase Pulse Generators are devices built by the Forerunners into their Halo installations. Halo's main weapon is powered by three phase pulse generators.Halo: Combat Evolved They amplify Halo's signal, and allow it to fire deep into space. The power levels are enormous. How they produce such prodigious amounts of energy is unknown. The generators could possibly emit a gamma ray burst. They are susceptible to close range EMP (Electromagnetic Pulse) discharges, and destabilize if they come in contact with an EMP.Halo: The Flood, page 268
==Overview==
They are usually located within the vicinity of the Control Room of the Installation,Simon and Schuster - Halo: Hunters in the Dark - Read an Excerpt and the Generator Chambers are usually only accessible by air or via ducts used by the Sentinels.Halo: Combat Evolved, level Two Betrayals
===Installation 04===
As mentioned above, the Generators were located close to the Control Room, in platforms accessible via air.Halo: Combat Evolved, level Two Betrayals
Cortana had John-117 disable these while on the first Halo, in order to delay the Installation's activation so they would have time to destroy it, and to prevent 343 Guilty Spark from "Finding another way of activating Halo's final weapon without the Index." They accomplished this by turning the Shield Generators from the Mark V armour he was wearing into a crude, yet effective EMP bomb, that, once activated, knocked out the Master Chief's shielding for a short time.
===Installation 05===
It is not known where the Phase Pulse Generators are. It is possible that unlike Alpha Halo, it uses only one large generator, within the Control Room itself.Halo 2, level The Great Journey
This might be a shield generator for Halo, or it may serve as a power source for Halo. However, during the fight with Tartaraus, 343 Guilty Spark says that the "primary generators are coming online."
===Installation 08===
Two of the pulse generators can be found on the last level of Halo 3, Halo. Unlike the generators in Installation 04, these can't be destroyed and seem to be more protected, an example of this is that the glass in the room surrounding them is unbreakable and some more barriers have been placed in the perimeter.
These generators also seem to be weaker, as they don't have a continuous beam. The reason for that may be that the Halo wasn't completed at the time. These generators were likely destroyed in the resulting chaos of the Installation's firing sequence, this could explain why John-117 was not killed by the energy pulse seen racing past him in the cutscene at the end of the level.
