Saturday February 11
Past 24 hours
- Smooth data production

- No beam in the morning but Beam came back around noon
- HARP scans

Friday February 10
Past 24 hours
- Data production resumed at 8:30 pm
- High-Intensity Test (Naomi/Justin/Richard/Lubomir)
Shift Reports
Reports
- Statistics balance
- PARA 0/90: 19.6%
- PERP 0/90: 20.8%
- PARA 45/135: 20%
- PERP 45/135: 19%
- AMO : 20.6%
Issues
- 7 FCAL bases lockups
- DAQ "crashed"
Pending:
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- BCM calibration. Alexandre recommends that we request a recalibration of AD00C BCM.
Plans
- No beam for most of the day due to beam study (high intensity instability for Hall A & B)
- Production (300 nA, 2h runs) with cycle:
- 2 runs PARA (0/90)
- 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)
- RF day (no beam for 8hrs) Wednesday or Thursday
Thursday February 9
Past 24 hours
- Beam back at 11:25 pm
- Shift crew forgot to change the collimator from blocking to 5 mm and start moving the collimator while the beam was on
- HARP scans
- No beam from 10 am to 10:30 pm
Shift Reports
Reports
- Statistics balance
- PARA 0/90: 20%
- PERP 0/90: 18.9%
- PARA 45/135: 19.9%
- PERP 45/135: 19.8%
- AMO : 21.4%
Issues
- Pressure readings (Naomi)
- Beam energy variations from HALLD:p and HDTGR:p are anticorrelated (Alex. D)
- Timing calibration [2][3] (Annika)
- Move the collimator while the beam is on
- Bleedthrough (Alex D.)
Pending:
- Start Counter (Beni) - We do not understand why there is a mismatch in the software between start counter and tracking.
- BCM calibration. Alexandre recommends that we request a recalibration of AD00C BCM.
Plans
- Accelerator, at the 9 am troubleshooting meeting will decide the course for today
- Work on Optics either in Hall A arc (does not affect us) or machine (affect us => no beam)
- High-Intensity Test
- Collect 100M events in production (sparsified) mode for beam currents of 900, 750, 600, 450, and 300 nA.
- Start with 900 nA to set the HV for the drift chambers, use Richard’s tool to set the TAGM thresholds and turn off the TOF and TAGH channels where the rates are too high
- Take a run at each current setting with these conditions, followed by a few runs at 300 nA with matching HV settings for comparisons.
- Richard also requested that we take a small amount of mode 10 (unsparsified) data at the high currents as well, which should take a few minutes for each setting.
- Production (300 nA, 2h runs) with cycle:
- 2 runs PARA (0/90)
- 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)
