Difference between revisions of "Run Planning Meeting Notes, August 13 -17, 2020"

Revision as of 08:20, 14 August 2020

Last 24 hours
- Stable-ish beam through yesterday to this morning, ~1.3 B triggers collected
- Beamline Turbo pump controller failed, Keith
Reports/Issues
- Need to pay special attention to the coherent peak position
  - Amount of adjust (to the coherent peak) is increased (45/135) each time we change orientation
  - Amo to 0/90 para requires (Beni)
  - Beam drift due to lost beam lock.
Pending issues:
- TagM card issue:
- FCAL remote controller PDU reset. (No reset planned for other three PDUs)
Run Plan
- No long beam trips, no harp yesterday. Next harp scan?
- Production
- Hall C path change tentatively at August 24th (for three days). Question regarding beam stability and maximum current is raised to Jay, being discussed amount experts. Possible solution: tune beam two a shift to stabilize the lock; Use AD00 BCM as BPM, etc. Jay will get back to me.
- CPP installation:
  - CPP's preference: schedule the CPP test after Aug 21.
  - Maintenance schedule to be decided.

Announcement
- Current run period has be extended to September 21.
- Updated shift list
Last 24 hours
- Unstable beam yesterday swing shift due to Hall C Moller measurement: 4:00-7:00 pm, 350nA tripping off AD00, unstable 240 nA available.
- Stable beam established after 7:30 pm yesterday.
- Diamond (JD-105 45/135) alignment completed by Hovanes during his shift
- TAGH scan completed by Sasha during his shift [1]
Reports/Issues
- Monitoring link (Twice a day monitoring line) is slow last night. [2]
- DIRC LV tripped due to the current off during swing [3]
Run Plan
- Next harp scan?
- Production
- Hall C path change tentatively at August 24th (for three days). Impact initial 3 days of running without orbit lock (Hall A is off in the same time), 350nA beam will trip AD00.
- CPP installation:
  - CPP's preference: schedule the CPP test after Aug 21.
  - Installation to be completed during the next maintenance day. Date undecided, Jay will inform me as soon as he decided.
Report/test
- DIRC/COMCAL HV CAEN reboot test (Hovanes)
- Small beam energy-current correlation (Alex)
Pending issues:
- TagM card issue, any update?
