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 9 at 8:45
- Last 24 hours:
- Reports/issues
- DIRC LED intensity variation check
- Beam energy monitoring, RCDB averaging accuracy, and bleedthrough
- Communication error of Tagger NMR probe (Solved) [4][5]
- All our raid discs are close to full
- Solenoid downstream lead temperature decrease (Solved) [6][7]
- Run plan
- Continue production runs
Tuesday, September 8 at 8:30
- Last 4 days:
- Resume production runs after GEM/TRD deinstallation work (Fri. morning)
- 10h long downtime (Sat. Owl shift). Harp scan
- 10.2B triggers (R73038 - R73070)
- Reports/issues
- TAGM columns 4-6 are back (Nick, Richard)
- FCAL PDUs power cycled (4 times over the weekend [8] [9][10][11])
- RootSpy Make e-log Entry not working (solved) [12] [13]
- First look at beam polarization from rho decays for Summer 2020 [14]
- Fit to gain calibration constants for summer 2020 [15]
- Controls PLC alarm [16][17]
- CDC HV alarm does not clear while HV seems OK [18]
- CDC HV trip
- Run plan
- Continue production runs
- Beam study (4h) in the SWING shift (16:30 - 20:30, may vary). Rapid accesses are allowed. Lubomir and Tim are planning to install a small stand at the PS arm. It will take 2-3 h.
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
- Also, Sasha is working for crystal. And Nick is working for TAGM in tagger hall.
- Reports/issues
- Beam position (sharpness of coherent edge)
- Reconstructed Beam spot shifted --> Depends on the beam current.
- Beam position oscillation [19] [20]
- 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)
