Start of shift: Beam to Hall B. 2L18 drops HV.
5 mismatches the last few days, or 9 the past 2 weeks. This magnet had a loose rail that was fixed by DC Power on May 13th, so these mismatches probably aren't attributed to that. Not using this magnet at the moment but may in the coming days.
SL01B01 channel 5.
Current ramp is disabled so I'm not sure why it decided to ramp very suddenly after restoring from an RF trip, resulting in two MaxJuice trips. We set it manually back to where it was before and it seems to be fine now. I've turned the current lock off for now, since it's been stable without needing adjustment for quite a while.
Upstream halo rates and 2C00 IDX started to show evidence of drift in the machine. Sent 5 uA tune beam from C laser to 2R and made significant adjustments to NL and SL gangphase. Also made a single-point correction to 2S horizontal orbit using 1R06H corrector. Orbit restored to B within about a minute and a half of returning beam to them.
