I had been struggling to flatten orbits to FCup 1. Finally, I realized that I had neglected to select the Relative BPMs when downloading AllSave #26302, so i have been steering to the wrong Rels! Turns out it is much easier when you do it right ¯\_(ツ)_/¯

We can reliably get 50 uA CW to the ILD with the low energy set up (V=0, no flip, H=10.5 degrees) after some optics tweaking in 0L. Once the ced workspace is back up we'll be able to do an 0R match.
I was able to calibrate orbit locks and get them going as well as the energy lock with some investigation. Transmission is >.95 for all lasers, and B (fig 2) and D's (fig 3) relative orbit looks good. The current pain point is BLM trips. ILM0L02 cannot be lowered from what I've tried, and I had to result to a very low orbit vertically in 0R to lower BLMs.

Cavities came up without much incident. Cavities 5 and 6 not so smooth as the others. I was able to achieve the ODVH for cavity 5, but long term stability at that gradient remains dubious. Cavity 6 I left at 11.0. It was quenching at 11.5. I kept lowering by 0.1 and was still quenching at 11.2 The cavity had been quiet at 11.0 so I just set it back to 11.0.
Spreadsheet has been updated.

I couldn't turn on the 0R energy lock without it railing energy upwards even after setting BNOMs. Went to the BEM screen and saw that it believed the momentum to be -2577 MeV. Reconfiguring BEM worked to correct the energy, but the lock would still rail. I dialled in a 3e-4 dp/p offset based on average value and the lock now works.

Problem not yet resolved. Honeywell tech is consulting his technical support. The control program may need to be reloaded or the controller power cycled. Either action will require all critical equipment controlled to be switched to manual operation during the process. This includes the North LINAC and West ARC LCW Systems in addition to the North Access Cooling Tower pumps and fans. Technician should return either next Tuesday (2-17-26) or Wednesday (2-18-26).

For low energy injector setup, the beam at viewers after full cryomodule (0L08 and 0L10 and chicane) did not look correct. Harp scan were also not normal (see pervious logs). We have asked D. Turner to repair the setup_345 CED workspace. Meanwhile, by imperically changing the quads at 0L04 and 0L05, we can get a beam that can transfer to the end of the chicane with acceptable beam spots. CW beam up to 45uA was sent to ILD. We suspect the problem is the very low energy beam and the lack of Rf focusing in the second full module.

The first viewer walk is as found on design with the 0L match previously applied. I first changed the MQJ0L04 matching quad from 51.2 to 0 Gauss to minimize the spot at 0L08 (second viewer walk), Then adjusted the MQJ0L05 LEMi quad from -27 to -127 to round the spot at 0R05 (third viewer walk). This was completely empirical based on viewers with the input of Injector and CASA SMEs.
