1L25 Repeated Trips--Derated Cavity 2

Log Number: 3747475Logbook(s): Entry Makers: bcadeBody: 

At the beginning part of our shift 1L25 tripped repeatedly. Cavities 2, 3, and 4 would trip; the others pretty much stayed up. Upon examination of the waveforms, it was determined that cavity two may be a problem cavity. It was derated by 0.2 MV/m. Will monitor for subsequent trips.
