COMMENT ON Replace gun HV electrode
Good progress today - removed electrode from tunnel, found an systematic way to determine rotation in lerf lab (thanks Ben Schaumloffel and Max Bruker). Ready for S&A to remeasure tomorrow and verify we're now good to reinstall. Next tunnel vacuum work anticipated Monday or Tuesday, but may shift with several things still to determine.
COMMENT ON Laser Alignments of B67 Cooling Tower Pumps
Alignment of the remaining four pumps was completed. Pump vibration analysis was completed. A time to reconfigure back to five pump operation will be coordinated with Cryogenics to minimize possible impacts to ESR complex operations and complete this work task.

COMMENT ON SAM 2026 Box Supply Work Preventative Maintenance/interlock checks
Working under PTW - 11789. All high-power load connections have been removed from BSY1C. The DCCT cart has been moved back to Building 36. The high-power load was moved to the south access. All work for BSY1C is complete up to interlock checks, which will occur after all PMs are complete and closer to HCO.

R30-6 simulation with yaw misalignment
Introduced 1 degree of yaw misalignment into the R30-6 cathode by rotating everything else around the insulator axis.
Figure 1: No significant effect on the beam centroid, but note that the coordinate system is with respect to the photocathode normal, which is unrotated in this simulation, so the beam angle w.r.t. the beam pipe will be 1 degree larger (17.4 mrad). This would be noticeable but could still be zeroed with correctors.
Figure 2: This misalignment is beneficial from an IBB standpoint: ions above 180 keV or so are completely removed from the emission area.
