After running on the dummy target early this morning we're back to LH2 running. We'll be sitting here until tomorrow morning.

Beam has been smooth overnight and into the start of swing but they've had a few issues this morning, slightly trippy but it's chugging along.

During day shift tomorrow, we'll move the SHMS out to 9.91 degrees and then try and get the BCM calibration done ASAP after that.

>From there it should be pretty quiet, no planned downtime from MCC until Monday when they have the final set of beam studies. We'll be running at the next setting for quite some time too.

Jay has had a quick look at the substation voltage to see if there's any correlation to the HMS dipole trips we've been having fairly frequently during early swing shift - https://logbooks.jlab.org/entry/3675191 , doesn't seem like there's a correlation.

Behaviour may just be coincidental but if we see another HMS dipole trip at a similar time we may want to investigate further.

Gabriel Niculescu takes over as RC today after the 13:30 MCC meeting. I assume he'll also be having an RC meeting today at 3:30 in the counting house meeting room.
