The silicon tracker of the beam test engineering model of the GLAST large-area telescope

The silicon tracker for the engineering model of the GLAST Large-Area Teles cope (LAT) has at least two unique features: it employs self-triggering rea dout electronics, dissipating less than 200 muW per channel and to date rep resents the largest surface of silicon microstrip detectors assembled in a tracker (2.7 m(2)). It demonstrates the feasibility of employing this techn ology for satellite based experiments, in which low power consumption, larg e effective areas and high reliability are required. This note describes th e construction of this silicon tracker, which was installed in a beam test of positrons. hadrons and tagged photons at SLAG in December 1999 and Janua ry 2000.
