Triton Injector

The Triton Injector has components located at three different potentials with different systems:

Ground potential: Vacuum pumps: Titanium-Sublimation Pump (TSP) 2, Ion-getter pump (IGP)2, Turbo Pump, Roughing pump Vacuum instrumentation: Ion-gauge, 2 TC, creating "Good vacuum 2" condition Preaccelerator HV(-55 kV) supply Fumehood Activity Monitor Source Cooling Interlock controller (monitoring Vacuum status from GND, -55 kV, monitoring cooling status, fumehood activity, AC power status) (providing shutdown signal for source Gate-valve, ion source power, Preaccelerator HV.)

-55 kV potential: Vacuum pumps: TSP 1, IGP 1 Vacuum instrumentation: Ion-gauge, TC, creating "Good vacuum 1" condition Gate-valve controller, interlocked with GND-level controller

-65 kV potential: Ionizer Power supply Extractor V Supply Einzel Lens Supply Cathode V Supply Immersion-Lens V Supply CS Boiler Supply (Variac) All power is interlocked with GND-level Interlock controller: Ionizer Power Supply has Battery-backup and "10 second" interlock turn-down. All other Power-supplies are turned down fast by interlock.
