玻璃型镀铝二次表面镜的模拟空间环境辐照试验研究

SPACE ENVIRONMENTAL SIMULATION IRRADIATION TESTS OF ALUMINIZED GLASS SECOND SURFACE MIRRORS

摘要: 主要通过对镀铝二次表面镜先后进行紫外辐照以及电子、质子的综合辐照,并结合太阳吸收率和半球发射率测试,研究了低能电子、质子以及紫外辐照对镀铝二次表面镜热控性能的影响。结果表明,镀铝OSR具有良好的抗紫外辐照以及抗低能电子、质子辐照能力。

Abstract: Space environmental simulation tests were performed with irradiation by protons,electrons and UV on the ground.Degradation of aluminized glass second surface mirrors（SSMs） is measured and discussed in thermal-contral performances such as the total hemispherical emittance and the solar absorptance.The results show that aluminized glass SSMs has eminent radiation durability.
