- Past 24 hours:
- RF recovery during the day shift
- Beam recovery delayed due to (1) issue in the injector, resolved by evening, then (2) UPS battery needs replacement in the north linac.
- Issues
- low counts seen in bcal sector (logbook entry 3670196)
- Reports
- helium target refilled, ready
- trigger rate and beam flux history for Spring 2019 run
- Today:
- Production: 200nA, Al 10-4
- Run Plan
- Production running: when beam returns, check beam conditions as follows:
- do harp scans, both accelerator and Hall D radiator
- check radiation monitor rates in tagger hall and Hall D
- verify transmission in PSC and PS coincidence rates @ 200nA, 1e-4 radiator
- Beam studies planned for day shift on Monday
- RF Recovery scheduled for Tuesday
- Production running: when beam returns, check beam conditions as follows:
Friday, Mar. 22 at 08:45
- Past 24 hours:
- beam recovery, conditions checked, running resumed.
- Issues
- HV tripped on two inner FCal blocks (logbook entry 3670196)
- HV in CDC tripped, without alarm! (logbook entry 3670885)
- Reports
- collimator transmission drops again (logbook entry 3670862)
- Today:
- Production: 200nA, Al 10-4
- Run Plan
- Production running continues
- Beam studies planned for day shift on Monday
- RF Recovery scheduled for Tuesday

- Past 72 hours:
- production running on He target until Sunday 5:30pm
- continued running on empty target through Monday 8:30am
- now in controlled access, RF recovery underway
- Issues

- Compcal monitoring plots, timing shows double peak
- Compcal HV communication failure
- FCal HV communication failure
- FCal fadc scalers stop updating
- Accelerator tightens AC lock constraints
- Reports
- Today:
- work on solenoid during 9:00am - 12:00pm, warm-up to begin
- accelerator
- Run Plan
