[43.20] The Beam Test Engineering Model for the GLAST Large Area Telescope

E. do Couto e Silva (Stanford University), GLAST Collaboration

The Beam Test Engineering Model (BTEM) of the GLAST Large Area Telescope (LAT) was installed in a beam of positrons, hadrons and tagged photons at SLAC in December of 1999 and January of 2000. The beam tests demonstrated the technical feasibility of the LAT instrument design, based on silicon-strip detectors in the precision pair tracker and a hodoscopic configuration of CsI crystals in the calorimeter, for satellite-based experiments, in which low power consumption, large effective areas and high reliability are required. Highlights of the LAT technology will be presented together with first results from the SLAC beam test of the BTEM.

Work at SLAC was supported by Department of Energy contract DE-AC03-76SF00515.
