半导体多康普顿望远镜(SMCT)是为了在0.1-20 MeV的能带内探索伽马射线宇宙而开发的，目前或不久的将来伽马射线望远镜不能很好地覆盖这一能带。SMCT的关键特征是高能量分辨率，这是高角分辨率和高背景抑制能力的关键。为实现SMCT，我们开发了低噪声双面硅带探测器(DSSD)系统的原型模块。对DSSD的几何结构进行了优化，以实现尽可能低的噪声。开发了针对低噪声运行进行优化的新型前端LSI。我们报告了原型系统的设计和测试结果。对于60keV和122keV的零摄氏度，我们已经获得了1.3keV(半高宽)的能量分辨率。
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.
