Just checked 2L18-7 that had no gradient readback on GMES in open loop tuning on Tuesday 06/09/26 maintenance day. Changed out probe conformal after checking it and GMES is now indicating some flicker vice a constant 0 Mv/m as on 06/09. This means the conformal cable was probably bad on the GMES diode input. Cavity is presently GSET 0 and stepped off +100k away from last known position of -2.48 k but beam is back and will have to try to OLT next opportunity!

After bringing NL back up, looks quite a bit different than this morning. Noticing the profile seems to be rotating as it goes around the arc.

Cryo CAMAC Crate 12 in the South Linac alarmed on a crate controller error rate when the temperature elevated at that location (as measured by analog_Temp_ch2_12).

Placing a fan in proximity to the Crate seems to have alleviated the alarm.

OM05 in the NA went into alarm tried local calibration but wouldn't calibrate (low output error). Will investigate cause of error but bypassed sensor for now.
