2022 Winter SAD ATLIS Tasks

Phase 1 Region

  • Install 200 kV w/o field emission
  • Replace DR dipole => PO written week of Aug 30 for new DM at CEBAF, UITF and 2 spare coils
  • Replace noisy Wien 20A SCE =>
  • Repair leaky PCUP LCW fitting
  • Remake A2 joint
  • Replace harp
  • Install & test 200 kV kicker
Phase 2 Region
  • Possibly install solenoid/valve downstream of chopper => MMF mapping solenoids in Sep. Do we have 2-3/4" pneumatic beam line valve?
  • Install bright lighting => Walked area with FM. Waiting for follow-up.
