Run Coordinator: Susan Schadmand (757) 575-7540

RG/Analysis Coordinator (AC): Lamiaa El Fassi (630) 605-4259
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, exit the room through its door to the outside. Do not go to the hallway! Call the RC from outside. RC will call MCC to take the beam away from Hall B and also will inform other Hall B staff members.
- 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.
- ◊ Do not spend more than 15-20 min trying to fix a problem. With any issue, contact On-Call Experts or RC.
- ◊ Review these important links:
- - Recent Changes and Current Issues
- - General How-to for beam restoration procedures and Moller runs.
Run Plan, Nov. 7th - 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!
