Colleagues,

I looked at the six meter magnet needed for the NE spreader per Scott's comments last Friday.  This doesn't work because one can't extract the fourth pass beam without a drift between the two three meter magnets Ryan used. I didn't realize that until I looked at the orbits (oops). How long that drift has to be I haven't calculated.  This work was instructive nonetheless so I provide it to you and will submit this as a TN.

Launch points for the orbits were extracted from Ryan's Optim files and placed in the spreadsheet attached to determine launch positions and angles for each.

Jay
