3 MeV tests
In the following run, Gun Grid Voltage was set to 10.0 (Knob Setting) to maximize current.

Start from where I left from yesterday. Repeat the last measurement from yesterday, so I can reproduce yesterday's condition, and start from there.
The Gun grid voltage was set back to 6.42 (knob Setting), similar as the last run on yesterday.
