Sunday February 26
Past 24 hours
- Production runs
Shift Reports
Reports
- After coming back from the downtime due to the Hall-D dipole trip, the diamond needed to be realigned (thanks Hovanes for coming in to take care of this)
- Initial checkout of newly installed CCAL (Sasha)
Issues
- CDC HV AI needed to be disabled
- Ratty TAGM distribution
- Same pending issues as before...
Plans
- Production (300 nA, 2h runs) with cycle:

- 2 runs PERP (0/90)
- 2 runs PARA (45/135)
- 2 runs PERP (45/135)
- 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
Saturday February 25
Past 24 hours
- Beam came back at about 5:40 am Saturday morning after long downtime due to Hall-D dipole over-temperature trip.

Friday February 24
Past 24 hours
Shift Reports
Reports
- Two FCAL bases replaced (Mark D.)
- First look at 2023 beam polarization from rho decays (Alex A.)
Issues
- Pending:
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- TAGH hot channels w/ no beam
- Noise in FDC2 (Lubomir)
- FCAL11 crate problems (Sergey)
Plans
- Completion of CCAL installation

- 2 runs PARA (0/90)
- 2 runs PERP (0/90)
- 2 runs PARA (45/135)
- 2 runs PERP (45/135)

Thursday February 23
Past 24 hours
- Production runs
- Cosmic run in raw mode when beam was down: Run 120800
Shift Reports
Reports
- New prototype in PS test stand: [1] (Sasha)
- CCAL ready for installation: [2] (Sasha)
- Accumulated statistics
Issues
- gluon04 spontaneously rebooted itself... which killed process providing main trigger rate to epics.
- DIRC LED Pulsers different from reference? -- midway through run.
- TAGM waveforms (Beni)
- Quality of coherent peak? Compare [3] from 2/15 and [4] from 2/22 and another for 45/135 perp: [5]
- Pending:
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- TAGH hot channels w/ no beam
- Noise in FDC2 (Lubomir)
- FCAL11 crate problems (Sergey)
Plans
- Completion of CCAL installation: possible during MCC work in NL tomorrow morning ~8:30 for about an hour.
