3 MeV tests

Electron beam tune is same as yesterday, tuned for 11.5 region.

Start from where I left from yesterday. Repeat the last measurement from yesterday, so I can reproduce yesterday's condition, and start from there. Yesterday, the sweeping magnet added to the end of the 3rd triplet magnets to sweep the beam.


The Gun grid voltage was set back to 6.42 (knob Setting), similar as the last run on yesterday.
