2015 NSF Proposal
November 13, 2015
Mention how construction of R1 illustrates the groups level of investment in Hall B's physics research program. The group's involvement will continue by training students in the calibration of the CLAS12 drift chambers. Olga Cortez has already been contributing in this manner.
Annual Project Report
Reviewed NSF proposal. Reviewed PAC proposal for CLAS.
Software beta testing. Particle vertex reconstruction.
Simulations for upcoming Run Group C experiment in Hall B. Moller background simulation to evaluate beam line shielding design.
Below is the Xbj distribution predicted by clasDIS using an 11 GeV beam.
Below is the electron scattering angle predicted by clasDIS using a 5 GeV beam to benchmark the simulation to experiment E00-108. The distribution for several Xbj bins used in E00-108 are shown.
