✦ Synopsis

The Gamma-ray Large Area Space Telescope (GLAST) is an astronomical satellite mission to explore the gammaray universe from low earth orbit, scheduled to be launched in 2007. The Large Area Telescope (LAT) on board GLAST detects gamma-rays by the pair-conversion process, using a silicon tracker-converter and a CsI calorimeter. A total of 880,000 strip signals on about 80 m 2 of silicon are processed by the readout electronics. Two custom ASICs, the front-end readout chip (GTFE) and the readout controller chip (GTRC), are used in a front-end electronics module to meet the severe requirements for this space application. In this paper, production of the front-end electronics for flight units and their test results are described.
