Engineering Level Antimatter Injection Reactor.

Engineering Level Magnetic Constriction Segments. MCS (6) *Note: this Level contains explosive bolts to separate all antimatter subsystems in the event of catastrophic failure, these subsystems are deemed expendable compared to the population of the starbase. This system is controlled from Main Ops or Chief Engineer's Office. In addition, this level has Manual Ejection controls that are guarded and their use must be confirmed by the computer and also by the Chief Engineer and surviving senior officer in Main Ops. In the event that the computer cannot locate command crew, the ejection will take place on the authority of the most senior officer that the computer determines is still on board. The resultant shock wave from the detonation of the antimatter has been modelled at level 7. For this reason there is an Impulse engine and navigation controls to send this area to a safe distance before detonation.
