Abstract :
The Gamma-ray Large Area Space Telescope (GLAST) is a NASA mission concept under development by an international team for a possible new mission start in the year 2001. The instrument operates as an e+ e- pair conversion telescope and supporting calorimeter imaging gamma rays in the 10 MeV to 300 GeV energy range. The baseline design consists of a modular array of e+e$pair trackers formed from multiple planes of silicon strip detectors interleaved with converter foils of Pb. A matching array of calorimeters of CsI(Tl) are below the trackers. The authors present the requirements and simulations of the performance of this imaging calorimeter
