望远镜式空间带电粒子探测系统研制

为满足空间高能粒子环境探测要求,研制了一套数字化空间电子、质子注量率能谱探测系统原理样机。该探测系统采用了半导体探测器组成的望远镜式结构,并应用了数字化的信号处理方法,能探测0.5 Me V以上的电子和5~300 Me V的质子;具有能够实时测量、体积小、重量轻、功耗低及可靠性高等优点。对该系统的各探测器的能量分辨率进行了实验测试,结果表明:TSi半导体探测器的能量分辨率可达0.5%,Si(Li)探测器的能量分辨率约为1.02%,均在可接受范围(小于5%)内。

Development of space charged particle detection system of telescope style

A space charged particle detection system is developed for detecting the space electron and proton fluence rate spectra, with a telescope-style structure made up of semiconductor detectors, and digital methods are used. It can detect electrons of more than 0.5 MeV and protons between 5 MeV and 300 MeV. The system is characterized by light weight, low power consumption, small size and high reliability. The energy resolution of the system is tested. The results show that the best energy resolution of the TSi semiconductor detectors is up to 0.5%, and that of the Si(Li) semiconductor detectors is about 1.02%:both are within the acceptable range(<5%).
