Robert Runkle, SUNY Geneseo / Triangle Universities Nuclear LabTitle: A Monte Carlo Simulation of a Polarization Transfer Proton PolarimeterAuthors: R. Runkle, K. Fletcher (SUNY Geneseo); W. Geist, D. Kruse (TUNL)Abstract: A polarimeter has been constructed and calibrated to measure the polarization of 13 to 16 MeV protons emitted from the 3He(d,p)4He reaction near the 430 keV resonance. The polarimeter is based on 4He-p elastic scattering. It consists of a gas cell pressurized to 400 PSI with helium gas and CsI detectors mounted at the right and left positions, behind collimating vanes at 650. The effective analyzing power of the device has been simulated using a monte carlo code, GENNY. The computer simulation isbased on cross section and analyzing power data, as well as the complex geometry of the polarimeter. There is good agreement between the results of the simluation and results from a recent calibration experiment, performed with a narrow beam of polarized protons.
