Integrated trigger count

GlueX Statistics Run Sheet

MEDCON 5 restrictions (Bob May email)

1. adhere to counting room capacity restrictions
2. maintain 6 ft. separation (briefly passing another person inside 6 ft. while moving about the counting room is inevitable and is OK)
3. wear masks anytime more than one person present in the counting room
4. at MEDCON 5 the lab has no cafeteria services because eating "cafeteria style" (eating in common from prepared food) is inconsistent with COVID-19 controls. Staging food in the counting room to share is inconsistent with MEDCON 5 COVID-19 controls.
5. food and drink consumption - because it requires removing face coverings to consume - should be limited to packaged food and drink brought for personal use that is consumed while maintaining at least 6 ft. from the nearest person and ideally, consumed in a separate room from others.

Thursday, August 27

1. Last 24 hours:
   • Due to Hall C current increase request, accelerator experimented with the optics => MCC recommended a HARP scan, 1st scan and 2nd scan
   • Production
   1. Many short trips - beam stable for 5 min and then trips
   2. We lost 8hrs ie runs 72873 to 72876 cannot be used in analysis
2. Report/issues:
   • HARP scan - fit fails because of the beam trip, corrected by Hovanes
   • CDC HV tripped twice: around 16:00 and around 22:00
   • FDC HV tripped
   • no HV alarms for CDC and FDC but problem visible on online monitoring plots and HydraRun saw it
   • Hovanes reported a bug in the communication software which causes the alarm problems
3. Pending issues:
   • TAGM missing channels due to preamp (Nick, Richard). Update
4. Run Plan
   • Production
   • CPP test - task 1 to 4 during Ilya's shift

Discussion on trigger/DAQ tests for the SRC/CT
