Halting Beam to Hall C for Hall B Optics Tuning

Summary:
Finding that trying to take data for 2C match is very disruptive to Hall C beam delivery; lots of BLM trips, so leaving them off until data collection is complete.

The problem: Hall B beam was at tagger. Hall B profile is acceptable but halo is not. Ops believes there is an obstacle in the line because they can't steer the halo out. Hall B does not believe this.

Yesterday zone 1L11 was turned off to reduce phase slip in the North Linac. This screwed up the optics in passes 3-5 as seen in linked entry 4483462. Jerone figured this out and ungset-0 zone 11, which got things back to where they were after ORFP.

All of the IDX gamma detectors are shown in figure 1. Just those in the BSY region are shown in Figure 2. Jerone saw the high values in the two around the Lambertson, 2C00 and 2C00A, and steered using AT09V corrector to reduce values below 1 R/hr now, figure 3.

Katheryne Price has suggested adding a set of four in the Hall B line as Ops has no diagnostics which can see beam scraping. I didn't recall this when Keith Cole asked me re 2026 SAM. I'm cc'ing both in this email. If we can find $25K, we should do this.

We will be trying an AT-2C match in pursuit of smaller beam at 2C21/24 next. Decision has been made to leave in the bucked dipoles at AT01/AT03 for, as the correction was attempted on the 26th (attached).
