Shift Schedule
- Shift Schedule Page
- Shift Opening: TO Sunday Feb 5th swing, please consider signing up
Requested Accesses to the Hall
- Looking to put SBS GEMs in DAQ during day shifts, need to fix a cable in Hall first
- Target team for oven heater check
Special Requests
- DC power did not access Hall during maintenance day for moeller magnet, would be good to coordinate in the future.
Notices for Shift Crew
- Check the How To page
- Pay attention to beam restoration procedures in the How To
- there is a procedure if beam has been away for 30minutes, and another procedure if machine has been down for tuning or something which may change beam profile. Communicate with MCC to figure out why beam has been down and to figure out which kind of restoration you should do.
- SL:
- production runs (1-1.5hr) and replays (50k replay for each run, ~two runs also with 200k replays per shift if possible)
- TOs:
- NMR every 4 hours
- Note the instructions for performing an NMR if there has been any changes to magnetic fields - see https://logbooks.jlab.org/entry/4124321
- Contact RC any time for any questions
