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.
