[Halla_running] Hall A RC daily summary July 31, 2025

[Xinzhan Bai]

Dear Collaborators,

Yesterday was an accelerator maintenance day, we didn't have beam for the day shift. During yesterday swing shift around 9PM, MCC started to send tune beam to Hall A. The beam restoration for Hall A was fast and efficient, see log entries: https://logbooks.jlab.org/entry/4431009 https://logbooks.jlab.org/entry/4431034 . Since that, we have been on production, no major issues (There is a problem raised in yesterday's swing shift during beam restoration, it is found that the Hall A Moller Quads shows reading back values, while according to the beam restoration procedure, they should read 0 and turned off. Checked with Jiwan, and was suggested to ask MCC to degauss this time, however, MCC is reluctant to do the degauss since we have been staying like this for months. Confirmed with Jiwan it is OK for now. See the log entries in the following sections.)

Since yesterday's Day to today's owl:
* Total Accumulated Charge at Kin3 so far: 70.15 C (Goal: 100 C)
* Total Accumulated Charge at Kin3 since yesterday : 0.86 C

Updates from MCC:
* Today is scheduled for pass change for Hall B, no beam is expected during the entire day shift.
