Vassu

• For passes 1, 2, and 3, each hole can be confined within one of the GEM locations.
• Hole 51 (r = 39 mm phi = -8 degrees)
  • This hole doesn't appear to move much in phi even with the large phi offset.
  • Keep it where it is so that we can understand and investigate the level of azimuthal defocusing at different radii.
• Each GEM rotation configuration (red, green, and black) contain either zero phi offset holes, negative phi offset holes, or positive phi offset holes.
• Efficiency at the edged of the GEMs?
  • Look at SBS GEM efficiencies.
  • How close to the edge of the GEM active region can we be?
• In progress: look into relative moller vs elasticC12 rates and their separation.
