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)

- KinC_x36_6
- DIS singles scans (NPS calo off), starting around 11am, takes about ~2h
- BCM calibrations, starting around 1pm including the Faraday cup measurements (0.5h), total about ~2h
Notices in Effect for Shift Crew
- IHWP change instruction: https://hallcweb.jlab.org/wiki/index.php/Hall_C_IHWP_Change_Procedure
Current Issues
- NPS crate #2 drops occasionally
- Not much reported recently, taking 30min runs (restarting a new run more often) seems helping
- BTA with low current - https://logbooks.jlab.org/entry/4256075
- Helper script: go_bta_config
- NPS crate temperatures:
Planned Access to the Hall
Special Requests
- Guard house work till Friday. Pay attention to the sign and follow the directions around there when coming to the accelerator site.
