- Past 24 hours:
- Beam orbit locks off
- Unstable beam, lots of tuning to get high current for Hall A/C. 25 trips/hr average and will work to improve when they identify a path forward.
- Compton Production:
- 2.86 billion triggers with Be (Runs 61321-61344)
- 0.24 billion triggers with no target (Runs 61308-61311)
- Occupancy plots - Sasha
- Compton plot run 61322 - Drew
- Energy monitoring - Alexandre
- Today (Thursday):
- Remove Be foil @ 8 AM, but leave cylindrical holding tube. Lockup hall at ~1 pm
- Production running with no target until 6 am Friday morning?
- Friday plan:
- LHe target installation:
- Hall open at 6 am for bleeding up beamline
- Other work in the Hall: start counter installation, others?
- LHe target installation:
- LHe target cooldown and filling schedule?
- Chris expects ~10-12 hours required for cooldown. He would like to be here during the initial fill.
- Possible plan: Run warm empty target for few shifts, start cooldown over the weekend and fill on Monday?
