Counting House is getting in touch with expert to see if beam profile is acceptable. Looks great at the tagger (linked) but 2C21 may be a little too wide in x (also linked).

If indeed it is too wide in x at 2C21, I'll back out of the last round of changes to matching quads and try to replicate results at 2C24 with the triplet. We were pretty close before, it shouldn't be too tricky!

Wasn't quick enough to get a picture of the debug screen before the faults cleared on their own. Will certainly keep an eye on it since this has been a problematic stack this year.

Steering looks a little weird. Noticed that small changes in 2T steering create large optical changes on 2C24 viewer. Taking a moment to re-check steering/separation.

No viewer photos of the evolving beam spot, but it looks like we may have been scraping a bit in the Lambertson, or otherwise going through a strange field region. I think(?) we're a little better centered now.

To justify the change to B laser phase since it has been a touchy subject, my foremost reason for doing so is that Yan told me I could. Otherwise, something a little more quantitative:

Fig. 1 shows interception with 5 nA to Hall B and 25 nA to D on 5/10
Fig. 2 shows interception with the same currents on 5/11and phase moved 2.2 degrees, after some slight steering to the center on apertures and slits. Not all that much worse for tweaking the injector on the fly.
Fig. 3 shows collinearity post-change through 0L and 0R, with the largest differences highlighted with color coded flags.
