Run Coordinator: Susan Schadmand (757) 575-7540

Daily RC/OA Meetings at 13:00 in CH Room 200C, and on ZOOM: URL Link (Meeting ID: 1611984219; Passcode: RGD-RC23), except on Wednesdays, which is on ZOOM ONLY @ 15:30 due to the conflict with the 13:30 MCC Scheduling/Planning meeting.
Important Notes
Do NOT change FSD settings without approval from RC or beamline expert!
- In case of medical or fire emergency, call 9-911 from a LANDLINE phone in the Counting House and inform the Crew Chief and RC.
- In case of evacuation of the Counting Room (e.g., due to a fire alarm in the Counting House), grab the shift expert phone and call the RC from outside. RC will call MCC to take the beam away from Hall B.
- If you have symptoms or a positive COVID test, do NOT come to your shift - instead, inform the PDL and the RC and JLab medical services immediately to arrange replacements.
- Remote shift: If needed, worker shifts can be taken from off-site. Inform the PDL and RC. Also, make sure that you follow the instructions under the "Shift Worker" tab as you need some lead time to set up!
- Note to shift takers, please:
- ◊ Read the logbook, be aware of previous 24 hours;
- ◊ Arrive at least 10 minutes early for shift change;
- ◊ Refresh the run wiki pages; look over them every shift:
- - Follow the expert/worker shift instructions.
- ◊ For advice, do not hesitate to call the RC first and foremost, day or night.
Current Issues
- Do not spend more than 15-20 min trying to fix a problem. With any issue, contact On-Call Experts or RC.
- NEW: when starting a new run after a successful end, do not go from Prestart, but Abort, Download, Prestart, and Go.
- Especially after the HWP change, check the SLM and FCUP charge asymmetry (Q-Asym on Beamline Overview); the absolute values should be less than 0.1%. If they are out of range, contact the Beamline Expert.
- NOTE: the beam position on BPM 2C21A is not essential during production; the beam orbit lock is on BPM 2H01.
- RICH:
- ◊ New RICH recovery protocol: see the "Shift Expert" tab the up-to-date information. Avoid unnecessary recoveries.
- ◊ RICH Sector 1 has three missing tiles; this is known, and no action by shifters is required.
- BMT/FMT/SVT: If new hot channels appear, call the MVT/SVT/MM expert Yuri Gotra (757-541-7539). These channels need to be addressed by the expert.
- ◊ Known Problem: BMT layer-1 on sector 3 (SEC3 L1) has a low occupancy since it's set at a low voltage due to subsequent strip trips; see logbook entry # 4215281.
- Tagger magnet procedure: If the tagger magnet needs to be turned off, tell the operator to use only the script for degaussing, NEVER do "by hand"!
- Change of target in the hall: In case of questions from MCC about the necessary controlled access, refer to the logbook entry #: 4196113 for the access requirements.
Run Plan for Thur., Nov. 2nd - Sat., Nov. 11th, 2023
P.S.: If the beam is widely fluctuating above 95 nA, please ask MCC to narrow down the fluctuation margin and give us the required 95 nA +/- 3nA based on 2C21A reading. They could put the beam current lock on 2C21A in case that may help with the wide fluctuation as it's currently done. We will keep the beam blocker IN while using this target combination!
