In working on the injector restoration procedure, and am unable to compete section 5.0 Steering from PCup to FC1/1D.
I'm unable to make it to FC1, experiencing beam loss (Fig 1 and Fig 2) at the chopper right after PCup is pulled, even with chopper off (Fig 4). No beam loss before PCup (Fig 5 and Fig 6).

Jerone and I went downstairs to double check the location of the 0L03A and 0L03 quadrupoles.
We wanted to check because both survey coordinates on CED and the "ACC-000-2845-0002" drawing imply that the 0L03 quad is upstream of the 0L03A one, which is the opposite to what it's in the Elegant deck and (implied by) the control screens.
To do a very non-rigorous quick verification, we left the 0L03A and 0L03 quads at 0 G and 477.9 G (as shown in Fig. 1) and, in the absence of a hall probe, we used a phone app that estimates the magnetic field flux in the phone's proximity using its magnetometer.
