Paper Abstract

The Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gamma-ray universe in an energy band 0.1--20 MeV, which is not well covered by the present or near-future gamma-ray telescopes. The key feature of the SMCT is the high energy resolution that is crucial for high angular resolution and high background rejection capability. We have developed prototype modules for low noise Double-sided Silicon Strip Detector (DSSD) system to realize the SMCT. The geometry of the DSSD is optimized to achieve the lowest noise possible. New frontend LSI optimized for low noise operation is developed. We report on the design and test results of the prototype system. We have achieved an energy resolution of 1.3 keV (FWHM) for 60 keV and 122 keV at 0 degree C.
