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.
Friday, September 4
- Last 24 hours:
- Data taking for DIRC/GEM/TRD finished at 6:40 am. (~4h downtime in the yesterday's evening)
- De-installation work in progress
- Reports/issues
- Beam position (sharpness of coherent edge)
- Reconstructed Beam spot shifted --> Depends on the beam current.
- Beam position oscillation [1] [2]
- Coherent edge
- Beam position (sharpness of coherent edge)
- Run plan
- Resume production runs after the work in Hall D (and tagger hall). The deinstallation work will be completed at ~10 am (11 am?).
- Harp scan before starting production runs.
Thursday, September 3
- Last 24 hours:
- Reports/issues:
- GEM/TRD occupancy plots
- RootSpy issues (Resolved)
- Solenoid ramping stopped at 800 A
- Test results of PWO crystals (test 5)
- Coherent edge at 0/90 PARA not so sharp anymore
- loss of lower gluex overview quadrant
- BCAL FADC scalers in visual GUI not visible
- RANDOM PULSER TRIGGER wrong frequency
- TAGM missing channels due to preamp (Nick, Richard). Update
- Run plan
- Continue DIRC commissioning until 6 am tomorrow morning.
- De-installation work from 6 am (will take 2 - 3 hours)
- Resume production runs
- Controlled access to the tagger hall to replace the preamp, should coincide with de-installation work? (Richard, Nick)
