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 remote connection information:

Current Status
- SHMS: 8 degrees, -9.2 GeV, 1x, 2x 1-7 off
- HMS: 20 degrees, -5.878 GeV
- 5pass beam, 40 to 60uA
- beam ramp rate 1uA/sec https://logbooks.jlab.org/entry/406490
Run Plan
- Continue data taking at setting 2. No special plan.
Special Task
- BCM calibration: https://logbooks.jlab.org/entry/4064522
Issues
- HMS Dipole and Q3 trip https://logbooks.jlab.org/entry/4064249
- SHMS HB vacuum https://logbooks.jlab.org/entry/4064884 and SHMS dipole LN2 level https://logbooks.jlab.org/entry/4064490. https://logbooks.jlab.org/entry/4064528 are red on magnet GUI. Those are know issues and monitored by Heidi. The latter could be addressed during next hall access.
- UNSER temperature has been mostly stable with the new controller but occasionally fluctuated https://logbooks.jlab.org/entry/4064634
- unfilled shift slots over the weekend.
Notes
- Brad switched the gas shed heat pump to "warm" https://logbooks.jlab.org/entry/4064368
- Two alarms are added to monitor SHMS Q2 vacuum while the vacuum gauge will be installed in the next maintenance day (thanks to Steve and Casey). https://logbooks.jlab.org/entry/4064546 https://logbooks.jlab.org/entry/4064936
- SHMS aerogel HV off and 50ohm termination was removed from the interlock https://logbooks.jlab.org/entry/4064052
- SHMS hood PMT 11 : https://logbooks.jlab.org/entry/4064301
To do
- UNSER calibration
- Install Q1 SHMS vacuum gauge (~3hr)
- calibrate SHMS Dipole LN2 valve during next access https://logbooks.jlab.org/entry/4064490. For now, monitor the ice accumulation if any https://logbooks.jlab.org/entry/4064528
