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
- NPS column 24,25 initial repairs done
- Cosmic data check showed a few channels need to be fixed https://logbooks.jlab.org/entry/4255522
- Summary of work done during the access:
- NPS work summary (https://logbooks.jlab.org/entry/4255429, https://logbooks.jlab.org/entry/4255443), thank you all for your hard work!
- SHMS encoder investigation (https://logbooks.jlab.org/entry/4255365)
- MQF3M01 water flow check (https://logbooks.jlab.org/entry/4255338)
- NPS crate #2 drops occasionally:
- Ben had a closer look at the runs with the issue. He thinks that it might be because npsvtp1 clustering was messed up, and this causes a problem for the FADC readout mask logic.
- Restarting a new run might be sufficient to clear it up.
- Ben will check if a firmware update could help eliminating some of the problem.
Accelerator status
- Hall B taking beam
- Maintenance + Beam study next Wednesday
Current Run Plan
- Short-term run plan: https://hallcweb.jlab.org/wiki/index.php/Short_Term_Run-Plan
- KinC_x36_6
- Spectrometer momentum and angles have been set for the kinematics. NPS angle is set to 7.5 deg instead of 7.4 (could only achieved SHMS angle to 23.8 deg https://logbooks.jlab.org/entry/4255364)
- We will start with setting up the corrector coils (Test plan is added to the MCC shift plan: https://ace.jlab.org/apps/pd/shift-plans/38835)
- Followed by lumi/background scans and potentially optics
- Do we want another polarization measurement next week? When? HallB will do Moller measurements on Wed.
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
Planned Access to the Hall
Special Requests
- Guard house work from next Monday. Pay attention to the sign and follow the directions around there when coming to the accelerator site.
