QuickPic - Hall B halo counter trip limits set for production values
Hall B UP. Taking 3 nA on carbon target
Hall B target harp scans: MQR2C23 got Y size good enough to run with
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.

Status Update
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.
Downtime Incident CLOSED: Setting up beam to B/C
Hall B complaining of bleed-through
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.
