Qweak Elastic GEM Profile
Elastic electron scattering profile at Z=-528 and Z=-558, the two limits of the GEm keep out zone.
Profiles generated by Neven using Katherine's Bash file representing the collimator design dated 8/8/07 from Paulo's Drawing "Hall -V QWEAK EXPERIMENT COLLIMATOR BUNKER SETUP UPSTREAM CLEAUP COLLIMATOR" # 67503-E-00021.
The previous profiles prior to this latest change in the collimator looked like:
The electron profile closest to the beam pipe center appears to be about 8 cm away from the beam pipe center now instead of about 7.5 cm.
