Wasn't quite making 10 uA at 400 (only about 8.5-9 uA), so raised the D laser attenuator setting to 450 to make 11 uA.

I linked this to two different ATLis's as a test. Neither of them have this log number linked in their ELog References section. Don't know if this is an issue with JELI or with ATLis, but I have assigned it to JELI.

2L05-5's GMES while bypassed is exactly correlated to linac current. Checked to see if it was stepped off correctly after the attempted revival on the 17th, and it seems that it wasn't. This cavity has known tuner issues, but we'll attempt to step off the tuner +20k and see if this fixes the issue.

Trims around the chopper just mismatched again. We've noticed these occur simultaneously with the VIP spikes.

This might just be a problem for me and a non-issue. SLMs are still working on the wall and it seems that I and others can pull them up on other computers without issue
