• General
  • Explain how beam loss near an MPS ion chamber results in a beam rate change (trace signal and describe logic in devices along the path).
  • 50B1 is an MPS stopper. What is an MPS stopper?

• Architecture
  • Sector repeater chassis
  • Signal type
  • Typical inputs

• General
  • When in BAS-II Mode:
    • which sector(s) is/are bypassed in the TIU system?
    • which other TIU inputs are bypassed?
  • How does a TIU fault interrupt beam?
  • When are the Linac slow valves automatically inserted? The fast valves?
  • Why are VVS and subbooster statuses TIU inputs? How do they differ from other inputs?

• Polarized gun
• Thermionic gun
• Damping Rings
  • PBL Inhibit
  • Septa Protection
• Positron System
  • HLAM/scavenger extraction kicker inhibit
