VIP2L258 HV Cable Needs Repair

1 day 13 hours ago
Log Number: 4468865Logbook(s): Body: 

Before 2L25 cryomodule was installed I load tested the HV cables for each pump. VIP2L258 showed to be overloading with nothing connected to it. This is indicative of rad damaged cable and will need to be re-terminated. An ATLis and epas will be made for the week to be done next week.

Mott checks

In preparation for tomorrow's beam study needing the Mott, I did a quick CODA run, inserted the viewers, and ran the target ladder through all important positions.
Had to do:
$ systemctl --user start platform
as user idaq per Bryan to get CODA to work. Need to document this in the wiki if not already done. Otherwise normal behavior.

Field Emission around NL22 as seen by the NDX detectors

1 day 16 hours ago
Log Number: 4468831Logbook(s): Body: 

Observed the field emission from the NL22 Cavity 1 earlier today. NDX NL22 photon dose rate increase was about 50 mR/h correlated with the gradient increase from zero to 10 MV/m in Cav.1. NDX NL22 and NL23 are currently set in the high sensitivity mode (10 pF capacitor and 5 sec integration time)
