keyword=Beam Position Scan
With raster size 2mm by 2mm, we scanned the beam around, with
the 15 cm norad target it (possibly skewed). We found hard edges in
both a Veto counter rate and in S1 at x=-2.0 and -8.5 mm. The rates
were pretty constant in between, except they dey decreased by 30% as we got
close to the -8.5 mm edge. Iny, we found edges at -3.2 and +4.8 mm, with
flat rates in between.
It looks like center of target is at x=-5.5 and y=0.8. We are using
this for subsequent running.
Is the opening of 6 mm in x and 8 mm in y reasonable?
