The GLAST (Gamma-ray Large Area Space Telescope) is being constructed to explore the high energy gamma-ray universe in an energy band 20 MeV -- 300 GeV. The GLAST has greatly improved angular and energy resolutions, and sensitivity compared with the previous instrument, EGRET (Energetic Gamma-Ray Experiment Telescope) on board CGRO (Compton Gamma-Ray Observatory). The GLAST is a pair-conversion gamma-ray detector and consists of 36 layers
of Silicon Strip Detectors and 7 layers of CsI calorimeter hodoscopes surrounded by anti-coincidence scintillator tiles. I will outline GLAST science from particle physics perspective. I also describe instrumentation of the GLAST and its construction status. |
