GLAST is a next generation $500-Million high-energy gamma-ray space-based
observatory designed for making observations of celestial gamma-ray
sources in the energy band extending from 10 MeV to more than 100 GeV. It
is scheduled to be launched in 2006 on a Delta II rocket.

The Large Area Telescope (LAT) consists of ~800,000 channels of
silicon-strip detectors to track particles, calorimeter detectors to
measure the deposited energy of the particles, and scintillator detectors
to provide cosmic-ray rejection. Electronics for the LAT contains several
mixed-signal custom integrated circuits.

The seminar will give an overview of the LAT instrument with a description
of the electronics.  The signal-processing integrated circuits being
developed to read-out high-energy physics-type detectors are reviewed.
Challenges are low-noise, low-power, and operation in space-environment.


Gunther Haller received the M.S. and Ph.D in electrical engineering from
Stanford University in 1990 and 1994, respectively. He is the head of the
Electronics and DAQ department of the SLAC research division. Gunther is
also the chief-electronics engineer of the NASA/DOE Gamma-Ray Large
