摘要: Abstract Extensive Monte Carlo modeling of a coded aperture γ-ray telescope based on high resolution liquid xenon TPC has been performed. Results efficiency, background reduction capability and source flux sensitivity are presented. We discuss in particular the development reconstruction algorithm for events with multiple interaction points. From energy spatial information, kinematics Compton scattering is used to identify reduce events, as well improve detector response few MeV region. Assuming 1 mm RMS an 4.5% FWHM at MeV, capable reducing rate expected balloon altitude by order magnitude, thus significantly improving sensitivity.
