HIGH ENERGY GAMMA PHYSICS WITH GLAST

The Gamma-ray Large Area Space Telescope (GLAST) is a space mission that will detect photons from the sky in the energy range between 10 keV and 300 GeV, scheduled for launch by NASA in 2007. Compared to previous missions, GLAST will have greatly improved sensitivity and ability to resolve γ-ray point sources. This report describes the detector design and performance and presents an overview of the physics goals of the GLAST observatory
