I'm not going to bother too much with the C laser at the moment as the orbit is a bit wacky off the cathode; if it gets better, so be it.

Some better centering through the choppers and solenoids improved the horizontal collinearity of A and B, with the remaining mismatch able to be fixed by tweaking chopper X phases. I am unsure whether one should prioritize collinearity through the 0I and early 0L, or through the late 0L and 0R. I decided to let the prior suffer to the point of being just outside our 0.5 mm spec in exchange for what seems like very good orbits through the latter.

With the booster properly phased again, 0L03 and 0L04 need to be checked. Both zones were around 23ish degrees off. Yesterday I had to add 0.2 MV/m total to the lock cavities relative to LEMi setpoints, perhaps to compensate for the booster phase being off, but today I had to reduce them by 0.2 MV/m relative to LEMi setpoints.

Found both cavity phases were not nominal. Crested both on the viewer (Fig. 1 & 2) and added the 26 (per Yan) degree offset to the seven cell (2L02-8). Set MDL0L02 for 6.74 MeV/c, cycled, and found that I needed to reduce the GSET of the seven cell to the value (10.09 MV/m) it was at for the prior run.

V Wien was already set to 0 degrees, H Wien was changed from 0 to 10.5 per recent email about CIS desired spin settings. Resteered mostly with correctors and a small reduction of MWF1I06.

At 8:40 am VTP0L04 started reading a high pressure alarm. This seems to be an after effect of an earlier event. At about 6:50 am the RF On/Off tool was used to turn off RF in the Injector and North Linac, after which pressure spiked. After vacuum stabilized it seems to have settled just at the setpoint for the turbo pump to turn on, causing it to turn on repeatedly. This was noticed and the pump was set to local mode and the pressure continued climbing very slowly for the next 1.5 hours until the event at 8:40.
