Follow-up Re: Injector Shift - 0L04-2 Upset
Log Number: 4526500Logbook(s): Body:
It appears that 0L04-2 became upset directly before the injector energy shifted. I pinpointed it by looking at the CRFP of all RF in the injector and it appears that the DETA suddenly shifted to -55 for some reason, the tuner brought the cavity back in, and DETA remained noisy for several minutes before some further chicanery that eventually resulted in the tuner settling back into the prior position. PLDE got much noisier during this period as well, and the second upset of DETA was coincident with a 5 MV/m GMES drop.
Downtime Incident CLOSED: 2L18 Dropped HV on Unknown Interlock Fault
