Hall C beam may be acceptable as is
Looking at the individual wires, the growth in X in 3H07B may be an artifact of beam motion. Harp wires move 1.5 mm/s. First three images are the X, Y, X wires of 3H07A. The first X wire is labeled U because at high energy synchrotron radiation affects it and I got tired of asking shift crews to look only at the third wire. Second set of three images are the XYX wires of 3H07B. Same intentional mislabeling.
I suggest the N-delta collaboration evaluate the beam as is before any further attempt is made to adjust X divergence.
SHIFT UPDATE: IHA2C04 looks good, preparing to send beam to xB tagger
IHA2C04 looks good after adjusting the MQA2C02 maching quad. After operator turnover, we are going to steer the beam up to the Hall B tagger dump for Owl shift to finish the optics to the target.
We will then turn our attention to Hall C restoration.
status update. Hall B extracted
beam is now matched reasonably well at 2C04 in front of Hall B. Tagger energized. We are going up and making sure its fine before starting Hall C CW delivery . A small focusing adjustment will be made in Hall C prior to CW. This evening, owl shift, the crew will setup Hall B while delivering to C.

status update
We rematched 5E using standard qsUtility. This improved both 5 and 6. We then adjusted 5R using the 6S01 viewer to produce a good incoming condition into 6E. The latest scan shows we are pretty close to what we want in 6E, likely good enough to extract to Hall B.
