5. Notes

Thursday, Nov 8 at 08:45

1. Last 24h:
   • TAC run with empty target, v-wire at 50nA, reduced field in PS (400A), low E TAGH counters on
     • logbook entry with preliminary analysis
   • 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
2. 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!
3. Reports
   • Monitoring
