A recent spate of detector trips in Hall B may possibly be traced back to current spiking upon beam restoration. In an effort to try and reduce the peak current, I turned the ramp rate down from 1.5 nA/sec to 0.8 nA. Not sure if this reduction was the thing that helped, but Hall reports fewer detector trips for the time being.
Cavity still has a ragged GMES. Looking through the archiver it seems this has always been the case, regardless of GSET. Tried open-loop tuning anyways and found that it was close to resonance but there might be something nonstandard going on with its tuner response.
GMES is still not very steady; taking more gradient out of it probably isn't a great idea unless we re-lem.
This was noted Yesterday afternoon (10/21/22). Issue is an instrumentation / readback problem as it has not affected beam operation. The screen shows faults on the RF Quick Page for that RFCM. Normal operating parameters are shown for the cavity. Problem to be addressed at the first opportunity.
Hall A requests 45 uA CW on polarized He3 glass cell. Raster is on (amplitude 1.3409 V, 1.2068 H). Ramp rate protection is on. Ion chambers are set for 45 uA with a 25% margin. MaxJuice is set to 50 uA.
Beam authorization: up to 60 uA CW
Operational restrictions for glass cells: up to 60 uA CW with raster always on
