Revision as of 14:47, 1 September 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.

- CPP de-installation, GEM/TRD installation started at ~ 6 am
- 0.07956B triggers 0/90 PARA
- CPP test from ~ 8:45 pm up to ~ 6 am [1][2][3]
- CPP installation finished at ~ 5 pm, beam came back at ~ 8:45 pm
Report/issues
Pending issues:
- TAGM missing channels due to preamp (Nick, Richard). Update
Run plan
- 6 am to 6 pm CPP de-installation, GEM/TRD installation
- Ramp down the magnet
- Preliminary schedule for DIRC/GEM/TRD running: continues through noon Thursday
  - 6 pm to 4 am, 10 hrs no-field run, 50nA on 10^-4 radiator.
  - 4 am to 10 am, ramp up magnet
- Diamond alignment?
- TAC run?
- Rastering study?

Last 24 hours:
- 4.27B trigger
- Beam down for 5hr30mn (weather + communication wrath)
- Nick and Lubomir accessed the hall
Report/issues
- DIRC, South Box Group 9 LV current draw
- CDC and FDC HV tripped
- BCAL pulser rebooted pulser test
- CPP test, task 1 to 4 not carry out because of beam down
Pending issues:
- TAGM missing channels due to preamp (Nick, Richard). Update
Run plan
- Beam expected to come back around noon
- Hall access to debug DIRC (and change crystals?)
- Production
- CPP test - task 1 to 4 during Ilya's shift

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
Run Plan
- Production
- CPP test - task 1 to 4 during Ilya's shift

Restricted or controlled access for 31st depends on if there is 1/2 rack available or not
