With all lasers enabled in BOOM Buddy, I did another QE scan, this time with the C laser, for good measure.

I applied power in all the cavities that are available in 1L05 and didn't see any gradient in any of them
probe cables were connected this morning and not sure what is causing this. It should be checked Monday

Re-running calibration for each laser to be on the safe side in case their spot positions are very different.

Replaced +24 VDC supplies used for interlocks on 1L24 and 1L25 before Lockup of North Linac. PSS removed their locks when the North Linac went to power permit so that I could throw the CPS breaker to insure we had fixed the door interlock and any other interlock problems before we PSS certified the last two N. Linac zones next week. All passed and got both into HV without further problems. Thank you PSS L. Krylach for the assistance in HV prep and waiting for power permit !

turned high voltage on in the zone after the probe cables were connected this morning.
When applied power it appeared that most likely probe cables for 3&4 are swapped.
applied power in 3 and no gradient in 3 but some in 4 and vice versa
I noticed the same with 5&6
These should be checked on Monday before turning rf on for any measurements
