总剂量探测技术的空间应用

空间辐射对飞行器可造成辐射损伤甚至失效，对航天员的生命健康安全存在着威胁。随着航天活动的深入，对空间辐射探测技术的发展提出了更高的要求。通过辐射敏感场效应晶体管（RADFET）探测技术设计研制了总剂量探测器，介绍了探测器的设计原理和测试数据分析，以及研究发展方向和空间应用展望。

Space application of total dose detection technology

Space radiation can cause radiation damage or even failure to spacecraft, which is a threat to the life, health and safety of astronauts. With the development of space activities, higher requirements are put forward for the development of space radiation detection technology. A total dose detector is designed and developed by radiation-sensitive field-effect transistor(RADFET) detection technology. In this paper, the design principle of the detector and the analysis of test data are introduced, as well as the research and development direction and the prospect of space application.
