We see a very slight shift on the MS, but not on A1 or A2 (visibly at least). The charge time of ~30 minutes is unchanged. IPM0I01B does not see it. This confirms it's most likely either at or after A2 and before the chopper.

Things are looking good at VIP1L06A, VIP1L07A, and VIP1L07B. We feel comfortable opening VBV1L05B

Seeing a slow increase in VIP1L07A. VIP1L06A looks good. Now we are going to open VBV1L07A to see how VIP1L07B is affected. We'll continue to watch this for the next half hour or so.

I am posting the progress of Hall C Spring 2026 experiment E12-23-001 (Polarizability, VCS2).

We need 4.7 days at 100% efficiency to complete the spring 2026 program.

Must: 4.4 days at 100% efficiency to finish the production setting 5c, 6c, and 7c.
Like: 0.3 days at 100% efficiency to perform elastics for 1c and 7c kinematics.

Sincerely,
Sangbaek Lee, for VCS collaboration

Follow-up Re: Injector beam motion and related conjectures

document with the harp and viewer work since 2020 at 0I02.

we ran without a top hat from April 2022 through the down starting in March 2023. The top hat has been in since then. Perhaps though the steering script to minimize beam motion at A2 could be used again to mitigate this until the root cause is determined?
