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
