摘　　要：针对K509玻璃基镀膜透镜空间带电粒子辐射效应,使用两种能量的电子和60 Coγ射线作为模拟源进行了辐照试验,并分析了辐照效应与轨道带电粒子辐射的差别.在此基础上,提出了一种针对镀膜光学透镜,使用低能电子和60 Coγ射线接续辐照,模拟空间带电粒子辐射效应的试验方法.The space radiation effect on K509 glass substrate coated lens has been evaluated. The irradiation tests have been carried out with different radiation sources and the difference between ground simulative radiation sources and space charged particles are discussed. In addition, a ground test method for glass substrate coated lens has been established by using low-energy electrons and successive 60Co y ray to simulate the radiation effects of space charged particles.
