COMMENT ON Miscellaneous RF SAM work
Replaced blower vane switch in 1L16 that was falsely reporting the fan was on (getting stuck closed) and confirmed new switch functionality. The CPS blower itself still needs to be serviced by Facilities for a different issue, so the fan should stay off for now so as not to trip again and take down the rack blowers and RFCM comms with it.
Verified proper grounding of transformer in 1L10 and cleared IC. 1L10 is now ready for PSS certification by SSG.

Wien chiller temperature setpoint further adjustments
There has been only one V-Wien HV trip off (90 deg spin angle settings) and associated vacuum spike with the chiller operating at 22 C. See referenced log entry.
With the Wien magnets set to ~ 4 A, I used a handheld IR temperature reader finding the Wien Cu and Fe yokes at 22-23 C. These are consistent with the chiller set point. The exposed section of the magnet coils is at 24-25 C.

COMMENT ON SAM 2025 Box Power Supply HCO
Aperture A2 opened all the way
With VBV0I02 and VBV0I05 closed, we retracted A2 up to the stopper ring.
Figure 1: vacuum at A2; peak 1 is valves closing, peak 2 is valves opening, small peak in between is A2 bellows moving.
Figure 2: before retraction; gap between the two metal plates of the linear stage is 39 mm at the "8 mm" position (as defined by aluminum bracket)
Figure 3: after retraction; top plate flush with stopper ring
Figure 4: gap is now 64 mm

Injector Steering Script Parameterization
Since I couldn't proceed with the main portion of my beam study I took some orbit response measurements to see how the spin flip solenoids effect the response.
Across all three spin flips (90, 0 -90), the orbit response behaves as you'd expect.
At 0 degrees, IPM1I05 shows relatively uncoupled response.
For 90 degrees, IPM1I05 shows essentially 45 degree coupling, with the vertical MBH1I04 corrector effecting both planes equally positive while the horizontal acts positively in the x and equally negative in the y.
For -90 degrees, IPM1I05 shows essentially -45 degree coupling, with the horizont
