1. Notes from the previous 24 hours:
   • MCC reports
   • Production Data with 58um JD70-100 diamond in the early afternoon
   • At about 6pm, we started low intensity scan as proposed in Justin's google sheet
   • For these runs: (i) Hovanes reverted the collimator position to the same value used in the previous current scan, (ii) We reverted to the previous value of the CDC window offset
   • [Beam Position Strip Chart, AC, PS Coincidence Monitoring https://logbooks.jlab.org/entry/3540484] (small interruption from 9pm-10pm)
2. Issues:
   • (fixed) Sean updated the CDC timing for the low intensity scan, see [1]. This has to be switched it back in production (see also this entry). How to restore production running (by Elton) [2].
   • Hall D BEM stopped reporting yesterday near 6pm [3] [AD]
3. Reports (some of these shown at the AWG yesterday):
   • Production vertex position before/after collimator shift (runs 40496 and 40509) [AA]
   • Pedestals Monitor FCAL, BCAL (run 41546 - production) [4] [SF]
   • Beam Trip map updated in CCDB [5] [DL]
   • low level monitoring [6] [TB]
   • yesterday AWG meeting [7]
   • Slope of the coherent peak high energy edge [8] [JS]
4. Planning:
   • updated run time chart [9]
5. Today's run plan Run Plan Google Calendar Accel. Run Plan Google Calendar:
   • morning: harp scan [10],[11],[12]
   • Production
   • Hall D low-current orbit lock test for TAC runs
   • Production: back 4 more

Thursday, March 2

1. Notes from the previous 24 hours:
   • Hall D low-current orbit lock test for TAC runs: succeeded in good horizontal orbit lock down to a few nA [13]
2. Issues:
   • DAQ crashes at go (Sasha fixed it) ~40 mins banu https://logbooks.jlab.org/entry/3540927
   • downtime - issue with one of the cavities ~1.5h (2L15-4 dropping zone from HV; Cavity bypassed; still dropping zone. EES-RF contacted.)
   • FDC trips during owl shift [14] [SF, VC]
3. Reports
   • cdc rates during current scan 41343-41347 [15] [BZ]
   • low level monitoring [TB]
   • beam [AD]
   • CDC pressure alarm [16] [CG]
4. Planning:
   • updated run time chart [17]
5. Today's run plan (TBD) Run Plan Google Calendar Accel. Run Plan Google Calendar:
   • harp scan
   • Sasha planning ~30 min run using the thicker 750 um thick converter after harp scan
