Gamma-ray Polarimetry
An astrophysics application of a low noise Double-sided Silicon Strip
Detector (DSSD) is described. A Semiconductor Multiple-Compton Telescope (SMCT)
is being developed to explore the gamma-ray universe in the 0.1-20 MeV energy
band. Excellent energy resolution and polarization sensitivity are key features
of the SMCT. We have developed prototype modules for a low noise DSSD system,
which reached an energy resolution of 1.3 keV (FWHM) for 122 keV at 0 degree C.
Results of a gamma-ray imaging test are also presented.Comment: 6 pages, 9 figures. Contributed to International Workshop on Vertex

GLAST Tracker
The Large Area Telescope (LAT) on board the Gamma-ray Large-Area Space
Telescope (GLAST) is a pair-conversion gamma-ray detector designed to explore
the gamma-ray universe in the 20 MeV-300 GeV energy band. The Tracker subsystem
of the LAT will perform tracking of electron and positrons to determine the
origin of the gamma-ray. The design and performance of the GLAST LAT Tracker
are described in this paper.Comment: 5 pages, 5 figues, Invited talk at Vertex 2005, Chuzenji Lake, Nikko,
