Revision as of 08:10, 27 August 2020

adhere to counting room capacity restrictions
maintain 6 ft. separation (briefly passing another person inside 6 ft. while moving about the counting room is inevitable and is OK)
wear masks anytime more than one person present in the counting room
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.
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

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
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
Pending issues:
- TAGM missing channels due to preamp (Nick, Richard). Update
