Excellent Data Taking Over the Weekend!

Key updates for the past 24h (Sat Day+Swing and Sun Owl): 
Our data collection has been exceptionally smooth over the past 24 hours (Saturday Day+Swing and Sunday Owl shifts). We effectively utilized 91% of the available beam time, with MCC delivering 19.44 hours of beam to Hall A, of which we collected data for 17.64 hours. The 1.8 hours of DAQ downtime were well within acceptable limits and included routine tasks like run changes, CODA resets, and VTP reboots for GEMS.

A key update for runs numbered 5125 and higher is the HCal gain coefficient update for four channels (details here: https://logbooks.jlab.org/entry/4412530). Minor issues with ECal cooling, ECal, and GEM DAQ were swiftly resolved by the dedicated subsystem experts.

A huge thank you to all the crew members and subsystem experts who sacrificed their long weekend to ensure such smooth operation of this experiment!

- Total Accumulated Charge at Kin3 so far: 45.89 C (Goal: 100 C)
- Total Accumulated Charge at Kin3 since Jul 02 Swing till Jul 06 00:00 : 3.52 C
- Estimated charge acquisition efficiency since Jul 02 Swing till Jul 06 00:00: 91.4%(3.52/3.85)

Run plan:
- Production on LH2 at 20 uA;
- Spot change postponed to Wed/9; evaluate polarization measurement before that

Current issues:
- Installation of Copper plate
- Monitor scalers and replay for missing/bad data that may require DAQ components reset/reboot/run restart
- Offline analysis: working on tracking reconstruction and processing time improvement
