We have checked injector orbits and then checked the bleedthrough again on the xB viewers, and we are still seeing similar amounts of non-colinear bleedthrough. We are currently doing step 2 of the plan (attached log entry), the QE Scan.

Summary of this morning's bleedthrough discussion.

Currently, it appears that the bleedthrough is coming from the C beam through the A slit. D beam is also going through the A slit. C beam is through the C slit. A few days ago, things appeared mostly colinear in the injector, but that needs confirmation today. Also the other night, adjusting the 3rd pass separator gang phase may have helped, though uncertain. This was performed at 40 uA.

It's interesting. We can see two distinct beamspots on each viewer. The left spot on 2C21 is the bleedthrough from the A slit. The right spot on 2C21

For reference, Figures 3-5 show the bleedthrough from C laser through the B slit. This is very close in profile and position when compared to just sending B beam, shown in Figs 6 & 7.

Tweaked third pass separation a bit, required a 2 degree change to gang phase.
