Current Status
- SHMS: 26 degrees, magnet polarity reversed for positron study
- HMS: 26 degrees, magnet polarity reversed for positron study
Current Run Plan
- Controlled access during day shift to fix HMS Dipole
- Continue with positron study as soon as HMS dipole work is complete
- BCM calibration early next week?
Notices in Effect for Shift Crew
- "cermode10" should be OFF for SHMS, ON for HMS
- 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 paddle study outcome: will run with paddles 1-7 off in S1X and S2x
- Should make offline runlist including some analyzed quantities (efficiencies, number of electrons)
- SHMS PRLO will be removed from ELLO for 8 degree running
- PRHI threshold will be reduced to current PRLO level
Planned Accesses to the Hall
- Controlled access in AM for dipole work
- See logbook entry and references therein for info on what happened
Planned Accelerator Configuration Changes
- Hall A pass change on Friday --> will start after noon
- Wein angle change on Friday
