✦ Synopsis

The proposed Tracking and Imaging Gamma-Ray Experiment (TIGRE), operating in the 0.3-100 MeV energy interval, will be an efficient polarimeter with a modulation factor of w 50% at 0.5 MeV. The polarisation detection parameters of TIGRE were estimated using a Monte Carlo simulation modified to include the polarization dependence of the Klein-Niskina formula. Using Compton scattering of low energy photons and approximately 3s acceptance angle after scattering, TIGRE will be able to measure strong sources with 20% fractional polarization at 3 g signiticance in a typical balloon-borne exposure and 5 5% during a 4-week satellite observation.
