Hall B would like the beam spot as close as possible to within 100x100 microns.

Figure 1: first harp scan with beam to target after optimizing orbit lock positions. Y > 200 um, X okay
Figure 2: MQR2C23 changed -300 BdL
Figure 3: Next harp scan. Y still not ideal, but deemed good enough to run.

Note for the future: Only a small change was made in MQR2C23 to make sure we were going in the right direction. That might be a good starting point for future iterations when/if necessary.

Iterated beam positions at 2C24A and 2H01 to minimize halo counts. Once hall was satisfied, updated positions, engaged, and calibrated their target orbit lock.

Hall B was seeing a large amount of bleedthrough on their halo counters from Hall D. It appears their beam blocker was massively amplifying the counts. After removing it, the counts dropped significantly.

Shift started with Hall B Optics tuning in progress, Hall C prep for Controlled Access since MBE3H05 not powering on, and Hall D taking 50nA of CW beam.

Hall B Optics wrangled in about 1700 once APEL understood the gameplan and quickly dialed in Optics for FC running. Tagger degaussed upon request. Ran to Faraday Cup with 1nA, then 3nA, dialed in positions, and took harp swipe.

Hall C took a quick access to power on MBE3H05 with no luck.

Checked Separation on viewers and bpms (no changes made), cleaned up GP and PL. Halo (Midstream) still seeing counts when sending D beam (CW) whether or not Hall B slit is opened or closed. Hall B removed collimator and all counts went away.

Doing basic sanity checks looking for the source of Hall D's bleedthrough, and the 1A SLM spot is very diffuse with 5 uA of Tune beam. Not sure when this started, but logging it here for posterity.
