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.
