Key updates for the past 24h (Sun Day+Swing and Mon Owl):
- Reasonably smooth production runs for most of the time
- Failures in GEM VTP4 and HCal VTP1 required restart runs during second part of Day shift; one GEM L14M01 trips recovered
- during Swing shift empty CDET histo in 5k replay required to restart the run
- from 4 to 7 AM DAQ has required attention related to GEM VTP, RC GUI frozen, HCal crates reboot; in the meantime beam has been off for about 15+20 min due to magnet mismatch and daily QE measurement

- Total Accumulated Charge at Kin3 so far: 39.08 C (Goal: 100 C)
- Total Accumulated Charge at Kin3 since Jun 25 noon: 6.67 C
- Estimated charge acquisition efficiency since June 25 noon: 88%

Run plan:
- Wein angle test for Moller exp. from 9:00 to 11:00AM; keep DAQ running (run 5029 for the Wein test)
- Continue production on LH2 at 20 uA;
- Spot change postponed to Wed/9; evaluate polarization measurement before that

Current issues:
- DAQ pretty stable during run, but may require multiple resets before start a new run
- offline analysis: working on tracking reconstruction and processing time improvement
