Cryo Daily Work Summary
COMMENT ON Post SAM FE onset measurements C75 and C100 cryomodules
It looks like most of the cavities on 1L07 and 1L22 can be operated. It would be great if some operators on swing and owl shift can run FE onset measurements on these two zones. The cavities should be taken up to quench in SEL mode with an admin limit of 22 MV/m. Please make sure that provide information on this ATLis as to the status of any cavities that are attempted. Also if there are any cavities where you can not exceed the previous operating gradients so that we can schedule some pulsed processing time. Once the data is taken Harshani or I will download it for further review.

FSD Masking Tool: Successful System Masking for: BeamLossMonitor
COMMENT ON Upgrade 2L03 to a C75 zone.
2L03 CPS: 454 Vac at input to High Voltage Transformer instead of 480 Vac. 0 to 10 Vdc control voltage at 9.8 V at the SCR Bank input when a full on voltage of 10 Vdc requested. Not sure .2 V is the total cause of the missing 30 Volts. Investigation to continue tomorrow. Techs: G. Kepler, A. Schoene, X. Gomez and S. Holben

COMMENT ON Install MOLLER ADCs, VME modules and connect BCM signal cables in Injector Service Building
All the fibers coming from another rack are in place, except short fibers that goes from ADC to the VME crate which are installed after installing Moller ADCs.
The cisco switch is already available in the rack with Hall-A network from the installed fibers. The switch might need a reset to have proper Hall-A DAQ subnet, which will be done in co-coordination with Matthew from CC.

COMMENT ON RF work for 2026 HCO
Completed Sorrenson supply replacements and checks in the North Linac. Replaced Sorrenson solenoid supplies in 2L22-8, 2L24-2 and 2L26-4 after removing and taking to Larry and Matt for repairs. Problem with supply current readback on 2L26-4. Only getting 15.68 amps on the readback instead of 31.5 amps. Checked control cable and connections but still getting low current readback even though it is set on the front panel adjustments. Will have to recheck and T/S tomorrow. Techs: Chris, Larry, Trey and Matt.
