After several trips on 2L10-7, found the tuner position went from -15184 to over 4 million. Spent some time bringing it back. Once brought back, was not convinced that the tuner is actually moving. Cavity was then GSET0.

I can't make sense of the numbers, but they're consistent with each other. In the top pane, .G is the voltage for the box supply. In the bottom pane, D.H is the voltage.

Photos of NDXs and IDXs can be accessed from https://opswiki.acc.jlab.org/wiki/Machine_Information

The earliest link, 4511306, has the relevant piece of the spreader. 4511366 has a darker version.

NDX2S01 is on the floor after ZAAS04. https://logbooks.jlab.org/entry/4511323 shows neutron dose during the initial steering but not from 0100-0230 when the 8E01 match was done.

just noting this, not sure if it would fix our transport issues to 8R, we'd likely have to redo shunt steering everywhere

Tried steering some orbit with 7R correctors first (no joy), MZA8S03 (found that it affects beam in 7L so corrections were made with 6R while adjusting ZA8S03). 8S01 Viewer inserted and running VL mode beam. Seeing spray but not solid beam. Once in a while, a glimmer of spray makes it to downstream 8S BPMs but nothing to write home about.
