COMMENT ON Replace gun HV electrode
Electrode back end successfully polished, cleaned, and installed on the electrode. The electrode was them moved to the tunnel and installed in the gun. Process went very smoothly. https://logbooks.jlab.org/entry/4548279
Gun Electrode reinstalled
The back end of the electrode was fully polished, cleaned quickly (thanks SRF cleanroom), reassembled without any change in alignment, and was moved to the tunnel and installed.
The process went very smoothly, with the new handles, giving us much better control inserting the electrode into the gun.
S&A is planning to help us set yaw tomorrow, and assuming successful alignment, we'll evacuate, leak check, and begin preparations for a bake next week.

Readbacks for the ADC and Digital Input cards are correct. Digital Output card doesn't seem to be responding to commands.
Claire (SW) is looking at it to verify correct communication/address.
Will continue HCO tomorrow after she has more time to investigate.
