Field Emission around NL22 as seen by the NDX detectors

2 days 2 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)

North Access Rack Room Very Hot

2 days 3 hours ago
Log Number: 4468826Logbook(s): Entry Makers: bjacobBody: 

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).
