I couldn't say if this is related to the energy jumps, or the injector discharges, or something drifting in the chicane, or the significant difference between C and D beam positions, or...

1L10 recovery

Summary:
Restoring 1L12 and 1L14 to compensate for 1L10 did not go as planned. Optics did not reproduce and our efforts to make it work failed.

Entry Makers: kpriceBody: 

We got in touch with RF on call about 1L10 and attempted to turn on 1L12 and 1L14 to make up the gradient. After running LEM and getting available 1L12 and 1L14 cavities phased up, we discovered the optics at 1E01 were substantially different from before the gradient shuffle. We called RF on-call again to let them know we couldn't make it work without 1L10; they're on their way and should be on site in about 30 minutes.
