[Halla_running] [EXTERNAL] Hall A RC Daily Summary August 23rd, 2025

[McMurtry, Jacob Thomas (rby2vw)]

Dear Collaborators,
The past 24 hours have been very smooth running. We started out at 20 uA, but near the end of day shift ECal folks increased thresholds in the bottom part of ECal, allowing us to run at 22 uA. They also tried increasing in the top half, allowing us to go to 24 uA. Ultimately it was decided that 22 uA setting is probably safer, so we have stuck with running there for now. The current plan is to continue taking production data at 22 uA on LH2 through the weekend.
Since yesterday's Day to today's owl:
* Total Accumulated Charge at Kin3 so far: 90.88 C (Goal: 100 C)
* Total Accumulated Charge at Kin3 since yesterday : 1.36 C
Updates from MCC:
* There are no plans except to send steady beam through the weekend. Hall A has priority!
** Hall C wanted to push for 60 uA, but are not going to spend too much time on that and will focus on at after Monday
** Hall D is currently down for the weekend and likely beyond (https://ace.jlab.org/dtm/open-events?event_id=21768 )
Current Issues and Hall activities:
* Target leak/pump failure, still holding steady around 2e-6 level
Shift Summary:
