高精度偏振探测是当前空间伽马射线天文的重要发展方向。3D位置灵敏CZT探测器具有突出的位置分辨能力，在空间软伽马射线偏振探测上具有很大潜力。本项目提出了一种基于3D位置灵敏CZT探测器的康普顿望远镜方案，拟结合实验和模拟两种方法开展研究。在该项目中将研制一套CZT探测器系统来测试其性能，尤其是三维位置分辨；然后通过蒙卡模拟对该方案进行优化设计，并研究其在轨偏振探测能力。

High-precision polarization detection is an important development direction of current space gamma-ray astronomy. The 3D position-sensitive CZT detector has outstanding position resolution, and has great potential for the detection of soft gamma ray polarization in space. This project proposes a Compton telescope scheme based on the 3D position-sensitive CZT detector, and intends to conduct research by combining experimental and simulation methods. In this project, a set of CZT detector system will be built to test its performance, especially its three-dimensional position resolution. Then, the scheme design will be optimized through MC simulation and its on-orbit polarization detection capability will also be studied.
