THE GLAST GAMMA RAY LARGE AREA TELESCOPE

The Gamma-ray Large Area Space Telescope (GLAST) is an international space mission that will study the cosmos in the energy range 10 KeV – 300 GeV, the upper end of which is one of the last poorly observed regions of the celestial electromagnetic spectrum to be explored. GLAST will have an imaging gamma-ray telescope vastly more capable than instruments flown previously. The main instrument, the Large Area Telescope (LAT), will have superior area, angular resolution, field of view, and dead time that together will provide a factor of 60 or more advance in sensitivity, and capability for the study of transient phenomena.
