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.
