Development of a Compton Polarimeter with Solid State Detectors

Abstract

A two-section Compton polarimeter has been developed out of a single Ge–Li detector. This device has nearly the same asymmetry ratio as the three-section polarimeter described previously, but has the advantage of a high efficiency. The asymmetry ratio of the device is calculated as a function of gamma ray energy. The polarimeter is also calibrated by gamma rays of known polarization from reactions 24Mg(p,p′) and 28Si(p,p′).
