MEDCON 5 restrictions (Bob May email)
- 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.
Wednesday, September 2
- Last 24 hours:
- 6 am to 9 pm CPP de-installation, GEM/TRD installation
- Magnet ramping down re-started at 3 pm and should be finished around 5:30 pm
- Start to take data at 10:15 pm
- Good data taking started at 4:00 am
- Report/issues:
- DAQ issues, random pulser was left on from the CPP run yesterday morning, which was swamping the DAQ with too many triggers
- Solenoid alarms for mass flow and diff temp
- Solenoid IOC rebooted
- FDC HV problems because wrong radiator settings used
- Ramp down wrongly initiated => stuck at 800 A
- RF recovery starting at 10 am, no beam expected until 3 pm
- FSDs vs RF system
- New crystals
- Pending issues:
- TAGM missing channels due to preamp (Nick, Richard). Update
- Run plan
- Ramping up magnet at 10 am
- Diamond 0/90 PARA
- 2 hours: focused FCAL trigger in GEM location (FCAL_TRACK_CENT_m9.conf)
- 8 hours: standard FCAL-BCAL trigger at 150 nA (low energy TAGH turned on)

Media:CPP_GEM_Test_install_schedule_Aug2020.pdf
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
- Many short trips - beam stable for 5 min and then trips
- 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
- Run Plan
- Production
- CPP test - task 1 to 4 during Ilya's shift
Discussion on trigger/DAQ tests for the SRC/CT
- Sasha requested 5-6 hours on Sunday to do these tests
Discussion on CPP and GEM-TRD tests
- Restricted or controlled access for 31st depends on if there is 1/2 rack available or not
