- Bleedthrough Different Beam structure after target change (Tuesday evening)
- Plan:
- Special run for BCAL, TPOL retracted, 5 mn beam at 200 nA, normal DAQ cfg
- 200 nA CDC & FDC turn off (3 shifts)
- 100 nA CDC & FDC turn off (2 shifts)
- MCC will run the Moller at helicity flip rate for HallB which might disrupt HallD beam
- If Hall A is back online today (unlikely most probably tomorrow)
- Check radiation
- HARP scan
- Bleedthrough run with 10 kHz random pulser, HallD laser turn off, and no beam for 40mn
