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
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)

North Access Rack Room Very Hot
DC Power noted that the rack room in the North Access building is very hot. This is not good for the trim cards in that room. The door to that room has been propped open as a mitigation but this is not a permanent solution. Additionally, the temp readback in that room doesn't appear to be representative of the actual temperature (see figure 1).
