2L05 CPS breaker reset. It tripped a second time in approx 5 to 7 minutes. Other than a tripped breaker no faults were found. Reset CPS breaker a second time. Approximately 1+ hour spent on epas. TEDF printer CS-12ps produced only blank pages, no epas forms.

As was requested by an injector SME, I checked the picoammeter background readings before and after the bleedthrough script testing. I plotted the PV that the script should be paying attention to (FCupsCORRECTED.VAL) and the FCupsrange PV, and proceeded to work my way up the range settings from to 200 uA. All appears to behave as I expect; the background measurement is very repeatable and consistent across the ranges up to the 2 uA setting when the last pA digit drops off. So long as we aren't measuring above 200 nA of bleedthrough, we should be good!

The shared-slit situation appears to be handled gracefully and, though I could only test the permutation currently available in the injector, I would hope the logic behaves properly for any possible situation. Figure 2 shows the liveplot of beam modes, slit positions, and the current measured at FC1 throughout all the non-Quick-Check measurements. Figure 3 shows the same but for the measurement with all halls selected. I was curious if 5 seconds would be enough for a stable measurement, but it seems fine enough from this view.

Was working on bypassing 2L17-3 as this cavity was SOS'ing, GMES unable to get above 1 and after a failed OLT attempt (couldnt get CRFP to 0.40 kW). While using the bypass script, the zone briefly dropped to Idle then to Filament. This occured twice while trying to bypass. Struggled to get zone back into HV.
