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.
