usual attenuator bump didn't clear the discrepancy between readback position and input position this time. Homed it just before the QE measurement; looks good for now.

1L04-8 tuner is stuck

Recent Log Entries -

Log Number: 4259528Logbook(s): Entry Makers: kpriceBody: 

tried to open loop tune 1L04-8 after it tripped and had trouble recovering. CRFP was ~3.2 even when cavity was only making about 5 MV/m. Detune angle, CRFP, GASK, &c., didn't respond to manual tuner movement. Would GSET0 but wouldn't be able to walk it off resonance, so chose 3 MV/m as a low, stable-ish gradient until it can be sorted out.
