Fig. 1
Setup as found. Prebuncher ON with 0I04 Viewer 'Inverted?' - (Bottom left) xB [120 degree] 12 o'clock, xA [240 degree] 8 o'clock, xD [0 degree] 4 o'clock. (Bottom right) xC [240 degree] 8 o'clock & shared with xA. (Top) Boom Buddy slit setup says xA & xD share the 'A slit' however lasers are really configured in such a way that xC & xA share the 'C slit' while xD goes through the 'A slit' and xB goes through it's usual 'B slit'

We were able to first go over performing spin flips and steering out orbit through the coupling, and then proceeded to go over what is necessary for larger Wien angles. I had wanted to go over how to optimize transmission, but CW was inhibited. We have reverted to end of run production settings and steered to rels.

Injector practice (pt.1) PCup --> FC1/1D

Setup as found

Fig. 2
Setup with Chopper, pre-bunch, bunch --> OFF

Fig. 3,4
Beam to FC1 after centering beam on 1I06 viewer. Wire Sums on 0I05 ~15 and 0I06 ~16.6.
* Realizing that a happy medium between BPM 1I05 'zeroed' and viewer 1I06 'centered' was NOT the way to proceed. Beam stuck at chopper after steering with MHD0I01AH/V, MBH0I04H/V, & MBH0I05H/V. Using MBH1I04H/V to center beam on 1I06 viewer was needed to get to FC1.
