[17.17] The Gamma-ray Large Area Space Telescope (GLAST): Instrument Technology Development

Peter F. Michelson (Stanford University), GLAST Collaboration

The Gamma-ray Large Area Space Telescope, GLAST, is a satellite-based experiment under development to measure the cosmic gamma-ray flux in the energy range from 20 MeV to 300 GeV. The primary telescope for the mission is a pair-conversion telescope. The telescope design includes a precision tracker/converter section based on silicon-strip detectors, a CsI scintillating crystal calorimeter arranged in a hodoscopic configuration, an anticoincidence shield that is an array of plastic scintillator tiles read out with waveshifting optical fibers, and a powerful distributed data acquisition and triggering system. The design and expected performance of the telescope are presented along with results obtained from a high-energy beam test of a prototype.
