Degrading klystron drive was discovered at the end of the maintenance day yesterday, and GASK is maxing out trying to run at 70 uA to Hall C. Derated it down to 8.5 MV/m and it's hanging in there aroun 8.3 V GASK, so leaving it there for now. Amp and drive output need to be checked on a maintenance day.

Figure 1: 24 MeV of headroom in the NL. Nice. Friday, if memory serves, we had ~7 MeV, dicey -- a C100 cavity away from not being able to make energy.

Figure 2: 45 MeV of headroom in the SL.

Figure 3: Using reCap, 5 cavities recovered yesterday still in use this morning.
