Theoretical Prediction and Simulation of Pair Polarimeter
Abstract
A pair polarimeter has been developed to measure the polarization of a photon beam of high energy. The polarimeter is a detector system which utilitzes micro-strip detectors for measurement of the angular distribution of e^+e^- pairs. This distribution is asymmetrical as a result of the photon polarization. Theoretical prediction of this asymmetry from numerical integration of the Bethe-Heitler differential cross section in the case of small scattering angles is found to be 0.26. After thorough validation of the code, the predicted asymmetry was implemented in a Monte-Carlo simulation. Comparison of theoretical predictions, simulated data, and real data will be shown.
