Aggregator
1L23 NDX Scan
Fig 1: Cavity 1 - No significant change from 8 MV/m -> 9.5 MV/m
Fig 2: Cavity 2 - Roughly 1R/hr increase in C100 neutron rates going from 10 MV/m to 13 MV/m. An additional 3 R/hr going from 13.0 to 14.8 MV/m. This large increase in neutron dose rate seems to start at 14.0 MV/m.
2L10-4 High GASK
The cavity started SOSing so I walked gradient down and was going to see if it wasn't tuned well. With a GLOD of -1.1 I could only get 0.06 kW of CRFP, and tuning showed we were on resonance. The attenuator is already at 0 dB. GASK has been rising for the past couple days.
