Figure 1: NL 1st pass BPMs, with Gain Pass set to Auto Select. Figure 2: Tried setting Gain Pass to Pass-1 forced, but blue readback PV IOCSE2:PassSel;r does not appear to be updating for the change. Same for Pass-2 through 6, and long pulse avg. Figure 2: IOCSE2:PassSel;r plotted, no changes. Figure 3: expected changes.
I might be mis-remembering how this works, and perhaps it is only supposed to work in Tune Mode. When correcting pathlength earlier in tune-mode, however, had same experience where selecting a pass would not update. Currently in CW.
Figure 4: 2L BPMs.
Hall is authorized up to 60 uA CW.
Per Operational Restrictions, with No Target, the hall may receive up to 40 uA CW with the raster off.
Raster is OFF.
Cooling Jets are OK.
Ion Chambers and BLMs are masked.
Harps IHA1H04 A & B will be scanned.
Figure 1: GP before pathlength checks. Figure 2: Pathlength w/C-beam 5th pass. Figure 3: Dogleg calc.
Note we have XGOFs dialed in Arcs 6, 8, 9 and A. Backing out of these before continuing. Figure 4: Backed out and re-steered in Arcs 8 and 9, Arc6 didn't need anything. All dp/p in the Arcs < 5e-4, within spec.
Figure 5: Pathlength after to 3C05. Figure 6: DogCalc, still going to need an Arc1 offset. Welp... unable to get pathlength to converge without the Arc 6, 8, 9 XGOFs. Backing out of changes using all-save and then by-hand the XGOFs.
