玻璃型镀铝二次表面镜的模拟空间环境辐照试验研究

摘要

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.%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.
