Arc 2 likes to throw our soft beam all over the place. I've been iterating between taking some steps with the bus while tune beam is running, letting 0R and 1A energy locks, injector and Arc 1 orbit locks run, then switching to viewer limited to try and find the beam. There's got to be a better way! Maybe fudge energy instead?

At long last! Had to do some fancy manoeuvring with LEM quads with SME assistance. Quads from 2L09 downstream are all at 64% nominal field. Now lowering arc 2 to try and get beam on 2S01 viewer.

Typed in the hours myself so I could sign the time sheet, but none of the fields are pulling in data from BOOM. The stamp isn't updating correctly either.

Camera seems to be alive, but there's no image. Maybe just a settings issue?

KRRP seems to be decreasing over time, but has been occasionally knocking 2L03-7 out. POFF sweep/optimizing didn't do anything to mitigate this and trips appear to be increasing in frequency. Just noting for now; we'll de-rate if it keeps up.
