Abstract

TIGRE, the UCR Compton gamma-ray telescope, uses multilayers of silicon strip detectors to track Compton scattered electrons, and CsI detectors to measure the scattered photon energy and direction. In this work, using Monte-Carlo simulation, we show the improvement that can be obtained when the electron tracking feature is added to a conventional Compton telescope. In simulating a Crab-like source in a balloon-background environment, the flux sensitivity for TIGRE is enhanced by a factor of 2.5 and the source location accuracy by a factor 3 over a non-tracking design.
