Popis: | 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 ∼50% at 0.5 MeV. The polarization detection parameters of TIGRE were estimated using a Monte Carlo simulation modified to include the polarization dependence of the Klein-Nishina formula. Using Compton scattering of low energy photons and approximately 3π acceptance angle after scattering, TIGRE will be able to measure strong sources with 20% fractional polarization at 3 σ significance in a typical balloon-borne exposure and ≤5% during a 4-week satellite observation. |
