TC wires ran and connectorized, temp sensor for CJC installed. All thats left is to connect sensors, configure each channel once the app/screen is available and verify functionality once sensors are placed in their intended spots on the filters. For now, we should be out of the way. Thank you to Marcy and Riad for letting us get in and finish this.

Ion pumps recovering well. With the exception of 1I03, they are all nearly back to their pre-activation values. I'll continue watching, and determine if the HV setpoints need to be adjusted after the vacuum fully recovers in case field emitters "woke up" during the higher pressure during the NEG activations.

Started functional tests of new parts installed in the prep chamber. Pressure was good - under 100 uA on the ion pump power supplies.

Put magnet on the long manipulator and moved in and out - very smooth. Used the back side of the HV chamber valve to pop the magnet on. Since the cam of the valve pushes toward the HV chamber, this direction of force helps close the valve more and is ok. If the pressure was pushing the valve toward open, I would not use a valve to push the magnet on.

The long manipulator seems to be slightly high compared to the side manipulator.
