2L26 Replaced Sorensen solenoid supply for solenoid #2 and adjusted all eight supplies for proper focusing current and trips. Restored zone back to HV after un-bypassing all eight cavities. Zone is ready for RF to be restored and phased. Techs: C. Kerns and T. Johnson.
2L24-1 helped Xavier connect and check filament bd. that was installed but not connected. Also, Trey and Xavier replaced the ram batteries on all four CPS control boards and the displays are working properly. Waiting for Xavier to complete IC/PTW with Sign on sheet. Kerns

Replaced the filament board for cavity 5. Discovered the ground hook wire coming apart so I replaced the wire and connection as well as other connections that slowly started to deteriorate.

Body: 

Worked on Cavity 2 which had not had a one hour run. Ramped up the power in pulsed mode. Heavy field emission. Reached ~11.5 MV/m and cavity started quenching.After several attempts to push past, I reduced the pulse width to 25 ms and was able to get the cavity up to ~14 MV/m and then started seeing WGVac faults. Managed to push cavity up to ~14.5 MV/m. Cavity started quenching again and looks like a hard quench. Stopping at this point.
Note: Fwd pwr at 5.5 - 6 kW which seems a bit high for a QL of 2.2E7. Need to check that.
