- In last 24 hours:
- Early Riser:
- Owl summary:
- Swing summary: https://logbooks.jlab.org/entry/3919677
- Day summary: https://logbooks.jlab.org/entry/3919504
- Helicity configuration changed for HallA https://logbooks.jlab.org/entry/3919498, no beam for several hours in HallC/B/D
- Updated Documentation on myaPlot https://logbooks.jlab.org/entry/3919509 (Elton)
- 0.2B triggers at 200 nA
- CCAL LEDs, 200 nA and 50 nA https://logbooks.jlab.org/entry/3919571 (Sasha)
- BCAL run, 81418, with TPOL converter retracted, 200 nA & PRIMEX/PHYSICS cfg https://logbooks.jlab.org/entry/3919569 (Elton/Mark)
- Issues:
- Bleedthrough https://logbooks.jlab.org/entry/3919567 (Beni)
- FCAL suspicious channels https://logbooks.jlab.org/entry/3919561
- Plan:
- Turn the magnet on and ramp to low current (50A)
- If Hall A is back online today
- Check radiation
- HARP scan
- Bleedthrough run with 10 kHz random pulser, HallD laser turn off, and no beam for 40mn

- In last 24 hours:
- Early Riser: https://logbooks.jlab.org/entry/3919395
- Owl summary: https://logbooks.jlab.org/entry/3919305
- Swing summary: https://logbooks.jlab.org/entry/3919178
- Day summary: https://logbooks.jlab.org/entry/3918973
- Production run started at 20:58
- 0.21B triggers with hot & cold Helium empty target cell
- 0.7B triggers with He target full
- Target cooled down and filled with liquid He4
- HallD cavity BPM calibration, https://logbooks.jlab.org/entry/3919129
- Gas bottle changed, https://logbooks.jlab.org/entry/3919183 (Elton)
- Issues:
- Solenoid alarm (Amy)
- Target software, https://logbooks.jlab.org/entry/3919168 (Carlin)
- Target, LH2 temperature interlock not changed, https://logbooks.jlab.org/entry/3918975 (Elton)
- LED skim, https://logbooks.jlab.org/entry/3918989
- Camera https://logbooks.jlab.org/entry/3918788
- 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
