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), grab the shift expert phone and leave the room through the "EXIT" door leading to the parking lot. Do not leave through the hallway! Call the RC once outside so the latter will call MCC to turn the beam OFF to Hall B and 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:
- ◊ Read the ESAD, COO, RSAD, and ERG documents found on the "Current RG-D Run Info" as well as the yellow folder in the counting room. Before you start your first shift on the current experiment, you must sign on the list in the yellow folder. Thereby, you confirm that you have read and understand their content.
- ◊ Read at least the previous 24 hours logbook entries to be aware of recent run details and changes;
- ◊ Arrive at least 10 minutes early for shift change;
- ◊ Refresh the runwiki page/tabs; look over it/them every shift:
- - Follow the Shift Expert/Worker tab's instructions.
- ◊ Do not spend more than 15-20 min trying to fix a problem. In case of any issue, contact the On-call Experts or the RC.
- ◊ Review these important links:
- - Recent Changes and Current Issues
- - General How-to for beam restoration procedures and Møller runs.
Run Plan, Friday, Nov. 17th - Tuesday, Dec. 5th, 2023
P.S.: If the beam is widely fluctuating above 95 nA, please ask MCC to narrow down the fluctuation margin and give us +/- 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.
