RC Meeting Information
RC Daily Meetings are at 11:00 (am) via Zoom and in person in the counting house meeting room (2nd floor)
- Zoom connection link: https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX
- Meeting ID: 161 701 5555
- Passcode: 288953
Useful Links
Hall status
- DIS singles data for LH2, LD2, Dummy. Carbon data need to be taken before switching to the Positron data taking
- BCM calibrations:
- https://logbooks.jlab.org/entry/4257267 (Faraday cup measurments)
- https://logbooks.jlab.org/entry/4257273 (BCM calibrations)
- Completed second production data cycle (first one with 8uA on LD2)
- NPS crate temperatures:
- Bill added them to MUNIN: https://hallcweb.jlab.org/munin/crates_det-day.html
- Temperature readings around ~95F for crate #4
- Escorted access: Confirmed AC working, Placed box fans for crate #2 and #4 (https://logbooks.jlab.org/entry/4257294)
- Asked facilities to set AC from 68F -> 65F
- SHMS hut temperature sensor to be replaced on Wed during the access
- Hall temperature reading frozen: https://logbooks.jlab.org/entry/4257295
- Ben will add FPGA temperature readings to DAQ info
Accelerator status
- West arc box supplies dropped off at 7am, downtime for ~2.5h
- Maintenance + Beam study on Wednesday
- Beam off at 7am
- Maintenance till around noon
- Beam study till 21:00pm
- Beam to the halls, ~22:30pm
- Scheduled can be shifted a bit if the maintenance work finished earlier
Current Run Plan
- Short-term run plan: https://hallcweb.jlab.org/wiki/index.php/Short_Term_Run-Plan
- KinC_x36_6, NPS at 7.5 deg, calorimeter at 6m
- Positron data taking today?
- Moller measurements on Thursday?
Notices in Effect for Shift Crew
- IHWP change instruction: https://hallcweb.jlab.org/wiki/index.php/Hall_C_IHWP_Change_Procedure
- BTA with low current - https://logbooks.jlab.org/entry/4256075
- Helper script: go_bta_config
Current Issues
- NPS crate #2 drops occasionally
- Not much reported recently, taking 30min runs (restarting a new run more often) seems helping
- NPS crate temperatures
Planned Access to the Hall
Controlled access. RadCon full survey starts around 9am.
- NPS: Julie, Josh, Aaron to look at the temperature read back issue (3 keys almost whole access?)
- Walk-thru at 1pm: Joe + 5 FIU students (6 keys)
- Heidi: checking Dipole, needs one hour
- Bill: SHMS hut temperature sensor replacement
Special Requests
- Guard house work till Friday. Pay attention to the sign and follow the directions around there when coming to the accelerator site.
