Revision as of 16:42, 11 December 2007

Elastic electron scattering profile at Z=-528 and Z=-558, the two limits of the GEm keep out zone.

The previous profiles prior to this latest change in the collimator when overlayed on top of each other 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.
