Summary
We will have an RC meeting today at 11 a.m.
Planned Access to the Hall
- Tomorrow (03/04) the hall will go to Controlled access 7:30am-8:00am for the NPS setup change (https://logbooks.jlab.org/entry/4259689).
- Bob Michaels and Hanjie would like to do some scaler tests with the DAQ during the downtime on Monday (see the comment to https://logbooks.jlab.org/entry/4259689).
- Julie wants to replace two faulty PMTs tomorrow during the access. Swapping those two pmts needs to be done while the calo is at 6 m and should take less than one hour. She also advises changing the FADC module that records block 1075 for a better one.

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
- NPS position for the next kinematics setting:
- 5m vs 6m (Charles): https://logbooks.jlab.org/entry/4258150
- Peter Bosted (https://logbooks.jlab.org/entry/4259621).
- Revised plan from Charles (https://logbooks.jlab.org/entry/4259689).
Current Issues
- Hanjie was concerned that some NPS crates have relatively higher fan temperatures (~95F). We put box fans for those crates. We also asked Facilities if they can lower the AC set point from 68F to 65F (was done on Wed 02/28).
- On Saturday (03/01) during Swing the heater power for both the loops 1 and 2 dropped to zero and recovered in a few minutes (https://logbooks.jlab.org/entry/4259365).
Future plans
- Monday (03/04): NPS setup change (https://logbooks.jlab.org/entry/4259689).
- Moller measurement next week (probably Tuesday)
