From the Hall D test done on 07/22/2026, the IA DAC settings are 40200 to zero the charge asymmetry with IHWP=IN - see linked entry.

The IHWP was taken out of the laser path (IHWP=OUT) yesterday around noon (see Figure 1 and second linked entry) but the IA settings were not updated for the values to zero the charge asymmetry. These values are 15260 and were found in the MOLLER beam study done back in June.

I changed the Hall D IA to 15260 - see Figure 2. When Hall D asks for change in IHWP, they should ask MCC to update the IA settings to the corresponding IA state.

C laser made (almost?) no power during the TMG test this morning. But there's no indication of it showing a problem afterwards; Ops kept using the laser successfully.
Causes to rule out:
1. No FSD trip
2. Amplifier output power fine
3. PSS shutters and fast MPS shutter read back as open

Not sure about the cause yet, will keep looking.

In concurrence with DC Power. Reset the fault at the interlock chassis, then on EPICS. Brought Arc 9 back up. Will cycle the stack twice, then cycle the trims. Then after a quick orbit check, we'll send back to the halls.
