JLAB Collimator design 6/14/07
On June 14, 2007, I went to Paulo Dedeiros's office on the 5th floor of the ARC cubicle 43 (500-43). I got him to output the pdf file below which describes the back side of the first collimator in Qweak.
I can then compare the dimensions on this version with the version I recieved back in 12/3/06.
summary
I do not see any major changes so I conclude that the collimator has not changed and the montecarlo results for the profiles of elastic electrons are still valid.
