Abstract
We report on the development of a CsI(Tl) hodoscopic calorimeter for the
Gamma-ray Large Area Space Telescope (GLAST). The GLAST mission is part of
NASA's strategic plan with a scheduled new start in the year 2002. The GLAST
instrument observes gamma rays in the 10 MeV to 300 GeV energy range and is
comprised of an e+e- pair conversion telescope and supporting
calorimeter. Our team, lead by Stanford University, is developing a tracker of
silicon strip detectors and CsI crystal calorimeter as part of a GLAST
technology development program supported by NASA and DOE. The calorimeter is
segmented in a hodoscopic arrangement and instrumented to provide both good
spectroscopy and moderate positioning (for shower tracking). We present here
the design requirements for the calorimeter and results of the technology
development program, including simulations and performance testing of a
prototype calorimeter in accelerator beams at SLAC, MSU, and CERN.
