Figure 1: INX2S01 is just after MZA8S03, as close to the junction between the two ZAs as I could put it.
Figure 2: all NDXs and sums, tune beam current in lower pane with range.
Figure 3: all IDXs. They rail ~4E3 R/hr unless one reduces the integration time (1 s now) or the capacitor value (1000 pf now, only other option 10 pf).

INX2S01 signal began as Ops worked on 8S steering after completing 7A ORFP, well before cycling the world stopped beam at ITV8S01 ~0230.

IPM8L24 is a little flaky, signal goes in and out even with consistent beam prior to cycling the world.

Pretty much flat through Arc7 and 8L.

We had beam all the way to 8R, ready to go forward. We cycled the world and then beam would not propagate past 8S01.

Beam is making it through 8L, with wiresum at IPM2L27 and no loss indicated on the M56 traces. We have zero wiresum on IPM8S01 and beyond. If we steer around, we can sometimes see a bit of snow on ITV8S01. No amount of steering with correctors or shunts gets beam through.
