South Linac sensor OM22 went into alarm on 9/13/2026. Signal drift was slow and adjacent sensors didn't indicate low O2 condition. There seems to be correlation with relative humidity changes.

Sensor OM22 was calibrated. Other ODH sensors in NL and SL checked and calibrated where necessary.

Cleanroom is in place, electrode is in tunnel (on cart in corner, do not disturb it), all supplies available for the vacuum work on Monday.

We'll do a very slow start, making sure to disable valves, lock out the laser shutter, and ensure all vacuum systems suitable before venting the gun. Details in spreadsheet as usual

Leak checked the HV chamber by opening to the prep chamber with the RGA on. (Extractor on throughout)

No hint of any leak found in the ceramic.
Fig 1: ion pumps during vacuum evaluation. All changes due to turning gauges on/off, degassing gauges, and opening/closing the gun valve. Nothing unexpected
