Riad asked me to go ahead and start setting up beam in viewer limited to the 1D. I Downloaded magnet setpoints from the 2024 run all save and turned off warm RF. I steered centered on solenoids and increased lense strength where the spot seemed unyieldy. Once I was to the 1D and centered through A1,A2, and the MS, I began phasing RF with CH1X as baseline phase as per procedure. First phasing prebuncher and buncher once I had A beam in the correct phase relative the CH1X. I then phased the other lasers and Ch1Y, setting gradient to about 120 viewer units.

All 4 beams phased in their run correct buckets (D might need a 180 flip) and making it to the 1D. I am nearly off shift so documenting my progress. I did have to strengthen MFA0I05.

I loaded the values for the prebuncher and buncher from the 2024 all save (pb=3.55, b=4.3 gset), and phased accordingly.

Loaded All save from previously known 140 KeV set up (wiens off), then threaded beam through to the 1D with all warm RF off. I had to make a few solenoid changes to get good enough beam for transport. I roughly centered through all lenses up to 1D. Attached is the viewer walk and the differences from the all save.
