- 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
Accelerator status
- West arc box supplies dropped off at 7am, downtime for ~2.5h
- Maintenance + Beam study on Wednesday

- 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

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
