Abstract :
LXeGRIT—Liquid Xenon Gamma-Ray Imaging Telescope—is the first prototype of a Compton telescope (CT) for MeV γ -ray astrophysics based on a LXe time projection chamber. One of the most relevant figures of merit for a CT is the detection efficiency for γ -rays, which depends on diverse contributions such as detector geometry and passive materials, trigger efficiency, dead time, etc. A detailed study of the efficiency of the LXeGRIT instrument, based both on laboratory measurements and Monte Carlo (MC) simulations, is presented in this paper.
