over the course of 10 hours of beam the cavity has tripped on arc faults 7 times in fault viewer and 4 phantom trips. I recommend GSETing this one zero

In order to trade with gangphase to get things on crest. we now have a distinct high energy tail on the 1A SLM, but that's peak E gain and lowest loss machine (including instantaneous loss. I suspect the low laser power and higher attenuator might be contributing to the increased longitudinal sensitivity to the upstream halo counters.
