- 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:
