Abstract
A method of determining the degree of polarization and the polarization electric vector angle from polarized cosmic sources in the energy range 100 keV to 10 MeV, has been developed for a pixelated CsI(Tl) photodiode detector plane by the determination of the Compton polarimetric modulation factor. The feasibility of the application of this method to the INTEGRAL mission to obtain a significant modulation factor and the resulting sensitivity of a detector to the above energy range is discussed. It is concluded that the INTEGRAL Imager will be sensitive at the three sigma level to a 100% polarized source of 55 mCrab in the 200-600 keV band, for a detector energy threshold of 120 keV, observed in 106 seconds.
