Emax completed on cav 7 and 8

Cavity 7:
High gradient not stable because of high oversaturation of probe signal. Able to reach ~18 MV/m with 3 kW, possibly more gradient with better control signal. Occasional WG Vacuum trips (~1/hr). No FE

Cavity 8:
Q_FPC = 1.40e7, Q_FP = 1.086e12
Emax 21 MV/m, strong FE of 20 R/hr, FE onset 13.5 MV/m
1-hour at Emax complete, no Tuner issues

Cavity 3:
Attempted to run +/- 15 kstep cycles, but ran into Abs Step limit

Both the positive and negative bulk power supplies for this trim rack faulted off, dropping the rack. Possibly airflow fault. Brought bulk power supplies back up once, then they faulted off again. Supplies stayed on after the second attempt.
