Useful Links
Current Status
- SHMS paddle study complete
- 26 degrees, setting 9 complete
- 26 degrees, setting 1 in progress
- Coffee maker working!!! (thanks Paul)! https://logbooks.jlab.org/entry/4052331
- New alarm on EDTM rate (will alarm briefly at run start, then should go away if EDTM set correctly)
Current Run Plan
- Complete 26 degrees, setting 1
- Continue to settings 2, 3, etc.
Notices in Effect for Shift Crew
- Pay attention to DAQ prescale settings
- Update EDTM setting to give ~25 Hz AFTER prescale (see table near DAQ computers)
- Use good electron fraction from 50k replay to estimate how many events will be needed to get required statistics
- For settings with long runs/low rates, can run full replay (run_full_hms.sh and run_full_shms.sh)
Current Issues
- SHMS PRLO/PRHI thresholds might be a little on the high side (https://logbooks.jlab.org/entry/4053287), but setting lower results in very high rates in PRLO
- Maybe for SHMS, ELLO should have NO calorimeter at all (i.e., just 3/4 + Cherenkov)?
- SHMS NGC PMT1 HV set back to 1700 (https://logbooks.jlab.org/entry/4052210) we'll need more elastic data to get efficiency
- Need to analyze SHMS paddle study ASAP to determine how we'll run 8 degree data
- cermode10 in the SHMS causes significant dead time (https://logbooks.jlab.org/entry/4052716) - should we turn it off?
- Need shift workers for Tuesday, Day (then Thursday, Day)
Planned Accesses to the Hall
- None
Planned Accelerator Configuration Changes
- Hall A pass change sometime soon (Tuesday?)
