In the past 24 hours:
Beam returned to the hall very quickly after the RF recovery and beam studies. We got beam in the Hall around 5 pm yesterday.

Completed harp scan  (https://logbooks.jlab.org/entry/4425165) and beam centering (https://logbooks.jlab.org/files/2025/07/4425181/summaryPlots_5423_SBS_critical_noGEM.pdf) before started production at around 6 pm.
We have collected about 0.72C since yesterday swing (63.58C of the total 100C).

 We had couple of DAQ crashes. Thanks the experts and the shift workers for fixing them quickly.

ECal ambient temperature started giving yellow alarm (https://logbooks.jlab.org/entry/4425471) around 1 am. Remote reset didn't stop the temperature rise (https://logbooks.jlab.org/entry/4425530). So, decided to go for an escorted access.
During the access, it was found that two AC units were having issues. We fixed one and still have a non-working AC unit in the Hall. Here is an elog from Don regarding this - https://logbooks.jlab.org/entry/4425567.
Don has requested for a controlled access to replace the AC1 unit. Hall is surveyed and Don is working on the ECal AC units.
After the AC unit work, we will go back to production.


We will have RC meeting today at 1 pm in the conference room in the second floor of the CH and on Zoom.
