Inj in Beam Permit, the rest of the main machine in Power Permit. Running beam to the 1D, PSS Mode 0.

Legacy zones in the South Linac are in HV. Box supplies in the main machine are off. 10 Amp trims are all zeroed. DC Power is coming in and locally ramping the racks down outside the Injector.

RF SME testing legacy zone klystrons.

LERF is in Controlled.

Beam studies concluded. Gun HV ramped down, and gun being locked out for photocathode heating and activation.

DC Power requested that we ensure that all trims downstream of 1D were zeroed before they turn off the racks locally. Checking against my allsave from last night after zeroing them, there are no differences downstream of 0I06A. DC Power is good to go to switch off racks.

Body: 

Ran program for Miram Curve once more for 2L15. This time let HV power supply warm up for at least 1 hour and curves looked as expected. See attached file ("2L15_20260821_MiramPlots.png"). Suggested filament values obtained after running program are basically the same as yesterday's. Should start Miram curve program once HV power supply has been turned on for at least 45 minutes, otherwise results could be skewed if filaments are set near 7 Volts already as they are in some of the tubes.
