KES
First iteration, beam only
GAMMA1 (blue) and E320_TARGET (yellow)
Step 1: find beginning of the beam. Script: both total counts as a function of YAG_VERT position
Step 2: full horizontal scan. Script
Step 3: full vertical scan.
Second iteration: after laser was walked to the beam (
MO_MAG (yellow) + GAMMA1 (blue)
Step 1: a) move the YAG up until we start intercepting the electron beam (left). b) shutter the e-beam and then move the YAG further: find laser (small spot, very much attenuated; plot: peak intensity (after hot spots are removed and a 2x2 Gaussian filter has been applied)
Step 2: a) moved the YAG very much up and drove it in from the side: stopped once we start to intercept the electron beam b) shuttered the electron beam, moved the laser to the YAG c) verified with a horizontal scan where we intercept the laser.
