Abstract

COMPTEL, the imaging telescope on board CGRO, uses Compton scatter kinematics to reconstruct the direction of the incident photon. On the basis of the gammaray detection principle, it can also be used as a gamma-ray polarimeter. A series of Monte Carlo (M-C) simulations have been carried out using a simplified geometrical model of COMPTEL. The aim is to investigate COMPTEL’s response to polarized gamma-rays. including the dependence on incident photon energy and incident angle. M-C simulations show that COMPTEL can detect the polarization of Crab pulsar (if it is 100% polarized) at a marginal level and determine the polarization angle to within a few degrees.
