CCD空间环境辐射效应地面模拟试验方法

摘要

针对星用电荷耦合器件（charge coupled device，CCD）在空间环境中遭受的辐射损伤效应，建立了CCD空间环境辐射效应地面模拟试验方法。从辐射模拟源、试验流程、最劣辐照偏置条件、不同能量质子位移损伤等效、质子和中子位移损伤等效等方面，研究了CCD空间总剂量效应、位移效应和单粒子瞬态效应地面模拟试验方法，为开展 CCD空间辐射损伤效应研究和加固性能考核提供了试验技术支持。%For the space environment radiation effects on the CCDs used in the satellites,the ground simulation test methods are built.The simulation test sources,test procedures,the worst radiation bias conditions,the damage equivalence of different energy protons,and the damage equivalence of protons and neutrons of displacement radiation effects on the CCDs are investigated to build the ground simulation test methods of total ionizing dose (TID),dis-placement damage(DD),and single event transient(SET) radiation effects in space environ-ment separately,which will provide the theoretical and experimental supports to the CCD space radiation damage effects and radiation hardening investigations.
