[clas_members] No RC meeting today - RC Summary for May 24- 25th

[Mathieu Ouillon]

Dear Colleagues, 

We will NOT have the RC meeting today.

This is the RC Summary of the last 24 hours starting from the day shift of Fri. May 24th: 

============================= May 24th Day Shift <https://logbooks.jlab.org/entry/4382495> ===============================
We have fixed most of our issues: HV AHDC, DAQ, HV ATOF, and the trigger bit. We are now starting to take data!!! 
One of the DREAM chips (AHDC) might be dead <https://logbooks.jlab.org/entry/4382675>. That led to some holes in the AHDC occupancy plot <https://logbooks.jlab.org/entry/4382661>. Raphael Dupré is aware, and it is fine for now. 
Raffaella updated the constants for the FT trigger <https://logbooks.jlab.org/entry/4382763> after the modifications made last week regarding the gain and temperature. 

============================= May 24th Swing Shift <https://logbooks.jlab.org/entry/4382748> ===============================
We continued data taking at 300nA on 4He. The DC HV tripped. There were some DAQ issues during the shift, fixed by the DAQ expert <https://logbooks.jlab.org/entry/4382939>. Despite these issues, we've been running smoothly.

============================= May 25th Owl Shift <https://logbooks.jlab.org/entry/4382999> ===============================
We continued data taking at 300nA on 4He. Felix purged the target. There was an issue again with the AHDC occupancy plots (empty), which has been fixed by the DAQ expert. MCC has done a QE measurement. Starting around 5 am, we had high counts in the upstream halo counters.

=========================== Game Plan ===========================
- Taking production data 325nA on 4He at 10.67GeV.

============================= BTA =============================
- ABU: 357.7 hours since Apr. 5th → 357.7 / (68.5 × 24) = 21.75%
- Day 50 of 137 scheduled: 50 / 137 = 36.5 %
- BANU: 6.95h from 7 AM May 21 to May 25

======================== Outstanding Major Tasks ========================
- Faraday Cup vacuum remains elevated — to be addressed after run ends

============================= runs ===============================
21834 --- FT trigger rate issue but still good
21835 --- FT trigger rate issue but still good
21836 --- 100M events 
21840 --- 100M events 
21843 --- 100M events 
21847 --- 54M events 
21849 --- 50M events 

Best regards, 
Mathieu Ouillon
