Here is the orbit and the LEM quad settings were Owl shift is leaving them. LEM quads are at 5@% percent of calculated values.

The process has been to lower the LEM quads to get a beam spot on the viewer, then trying to adjust phase of the Global NL gangphase, then zone, then cavity phase so that we round out the beam spot more of possible. Then we would steer the linac to flatten the orbit.

Did a viewer walk after we got towards the end of the linac, from the 0L to 1L22, the last viewer that we got to.

Checked the SRM tool to the 2R dumplette and found some systems not ready. Contacted operability to find out the status of these systems.

Operability confirmed that Arc 1 and Arc 2 dipoles as well as 2L25 are confirmed checked and ready by their respective owners. Other individual RF cavities that are marked not ready are either bypassed or GSET-0.
