Monday, Nov 12 at 08:45
- Last 72h:
- 6h down time on Friday due to HV issue on RF cavity 1L23
- 12h down on Saturday due to 1L23 and more
- 4h down on Sunday
- Completed the goal of 5 full cycles (2B events) on Sunday ~5pm
- Issues
- Reports
- Plans
- System Recovery (Monday 07:30, 6h+): switching back to 8.8GeV running?
- Beam Studies (Tuesday 08:30, 8h): installation of beam pipe
- Notes
Friday, Nov 9 at 08:45
- Last 24h:
- >80% beam available, >95% used
- completed 2nd cycle
- harp scan ongoing
- Issues
- Sluggish CSS during the day, investigating
- Tagger dump BPM AD00c
- Reports
- Plans
- Beam Studies and System Recovery switched
- System Recovery (Monday 08:30): investigate water leak in tunnel, ~3h
- Beam Studies (Tuesday): high current test, halls A, B and C have to stayed locked, D optional
- Notes
Thursday, Nov 8 at 08:45
- Last 24h:
- TAC run with empty target, v-wire at 50nA, reduced field in PS (400A), low E TAGH counters on
- Harp Scan
- Beam tuning (deferred)
- Data taking with reduced PS field, coherent edge at 7GeV
- TAGH Rates (Amo), (Diamond), Coincidence Rates
- Low energy running Trigger Spreadsheet
- RF problems in the night
- Issues
- PS and PSC coincidence scalers frozen, ps_client running on gluon100 restarted, instructions in hdops wiki
- beam position went awry, rates soared, reference module for IOC reading out 5C11B failed, replaced
- EPICS froze for 2h, started working without intervention, now again unresponsive
- Target PTR turned off, do not ignore any alarms!
- Reports
- Plans
- Notes
