Optics on call primary and secondary have been consulted.

DC power came onsite to check control system upstairs. Nothing out of the ordinary. If something was misconfigured on the magnet we would see it in the control system. All coeficients and setpoints are where they were at last high energy run.

We tried:
1. Additional 7R->8S shunt/correction steering solutions.
2. 7R recombiner match to see if perhaps beam was blown at the end of the linac into 8S but didnt work.
3. Zeroing first three 8S quads and steering with ZA8S03 to eliminate quad steering but nothing.
4.
