keyword=Kin. 13Analysis for kinematics 13. Without q, omega and pmiss cuts we are getting about
370 counts in the two body peak for 2.0 M events which corresponds to about 2 1/2 hours of running, or 148 counts per hour. This is about 2 times the MCEEP estimates done by Paul Ulmer recently. A sample spectrum is shown below. With all the q, omega and pmiss cuts we get about 6 counts total or 2.4 counts per hour compared to the MCEEP estimate of 1.6 counts per hour. Note that Paul Ulmer used a lower luminosity than we are presently running with. He assumed 95 uA of beam and target density of about 0.5 g/cm^2 which is about 1/2 our present luminosity.
Overall we are very close to the MCEEP estimates. The picture on the left is without cuts and on the right is with cuts.
