Swapped out Fast Valve +165V power supply card for 1L27.
Still trying to find the culprit that is causing the VFV1L27 fast valve to close without vacuum faults.

Update: *fingers crossed, last update* No linac openings tomorrow, Wed 3/11. Next planned MD will be Tuesday 3/17, both linacs dropping to Restricted Access. Adding this task to the SAM Cal for that day.

Hi, thank you for working through scheduling thorniness. With a little bit of luck this will be the last date change.

We'll have a Maintenance Day Tuesday 3/17 during which both linacs will be opened to Restricted Access. That will be an opportune time to perform this patching. There is a slight chance the day shifts to Wednesday, but that would be the only shift entertained.

Fingers crossed, 3/17 works for all.

Riad asked me to go ahead and start setting up beam in viewer limited to the 1D. I Downloaded magnet setpoints from the 2024 run all save and turned off warm RF. I steered centered on solenoids and increased lense strength where the spot seemed unyieldy. Once I was to the 1D and centered through A1,A2, and the MS, I began phasing RF with CH1X as baseline phase as per procedure. First phasing prebuncher and buncher once I had A beam in the correct phase relative the CH1X. I then phased the other lasers and Ch1Y, setting gradient to about 120 viewer units.

All 4 beams phased in their run correct buckets (D might need a 180 flip) and making it to the 1D. I am nearly off shift so documenting my progress. I did have to strengthen MFA0I05.
