2L17 ramped to ODVH with the exception of cavities 5 and 6.
Cavtity five will just trip off on a P1 fault as soon as you try to raise GSET from 3.0 to 3.1. Finally stopped trying.
Cavity six was working at 3Mv/m. I tried to raise that one and got very unstable.

Cavities 5 and 6 need a little TLC.

The injector high current setup is combination of save #27234 by kazimi from gun to 0L01 and the second part from save #26214 by ywang from last year 1060 run.
The phases of the zone 3 and 4 cavities had to be adjusted. Energy was set (Fig. 1,2,3).
Orbit was steered in 0L and 0R (Fig. 4)
Fig 5 shows beam in chicane at high dispersion point.
Zero posed (Fig. 6) and saved Save #27236

For OWL shift crew:
I would like the owl shift to please set the Wien angle. 0 and 46.5 degrees. Then perform the match to NL and record the results. Please do not forget SAVE SETTING!

The lemi momentum miss in the linked entry may in part be due to the 3db change. Or the change may be due to the addition of a 3db attenuator. There are no RFLOG entries about such a change September 1-12, 2025.
