Asked to test out LEM after linked ATLis work. I used the NL for this test since there didn't seem to be any RF work on going that would negatively impact the gradient distribution.

It looks like things applied appropriately. It probably would've been a smart idea to capture the info page before applying the changes but at the very least the cavities responded to the LEM application.

Fudge also looked to have appropriate response.

Tested the bleedthrough measurement script:
1. Set up last run's configuration +A laser at 50 uA (700 nA to B at slit 20, 60 uA to C, 25 nA to D)
2. Selected all 4 lasers
3. ran the script
4. Immediately, script failed to recognize that A laser was set to C slit and closed C B, and D slits (i.e. all slits). This meant that it sent 50 uA to all slits closed and got a zero current readback (.0025 uA, the script does not subtract the DC offset from the FCupsCORECTED readback with beam off)
5. Did B slit correctly, measured the current through the slit at 20 and all other slits closed.
6.
