玻璃空间电离辐照着色损伤考核方法
|
摘要
针对空间电离辐照的复杂性,在玻璃空间电离辐照着色损伤动力学研究基础上,讨论了玻璃空间电离辐照着色损伤考核面临的问题,提出了一种动力学的考核方法。基于该方法,以K9-HL玻璃为研究对象,研究了特定轨道(近地点350km,远地点425km,轨道倾角51.6°)下玻璃空间电离辐照着色损伤过程,分析了特定轨道下玻璃空间电离辐照着色损伤特征,结果显示:K9-HL玻璃特征轨道在轨20年后蓝光区域透过率降低严重导致其必然呈现淡黄色,严重影响了其作为高性能无色光学材料的使用。此外,对玻璃空间电离辐照着色损伤~(60)Co-γ射线辐照考核方法的适用性进行了分析讨论,结果表明,采用~(60)Co-γ射线作为辐照源分析玻璃空间电离辐照着色损伤可能引入较大误差,造成该现象的原因是~(60)Co-γ射线在玻璃中的作用深度极大及考核方法未考虑色心弛豫消失。
According to complexity of space ionizing radiation,from study on kinetic of space-ionizing-radiation-induced coloration in glasses,this paper discussed problems faced in performance tests of space-ionizing-radiation-induced coloration in glasses,and a method of performance tests based on kinetic was proposed.Using this method,space radiation induced coloration in the glass serving in a given orbital(perigee 350 km,apogee 425 km,orbital inclination 51.6°)were analyzed.It can be seen from the results,after 20 years in the orbital,the blue region optical transmission of the K9-HL glass decreases severely,leading to the glass' s turning light yellow,and it certainly will do harm to the glass' s usage as a fine optical material.Additionally,the applicability of performance tests of space-ionizing-radiation-induced coloration in glasses using ~(60)Co-γray was discussed.It can be seen from the results,it gives to a large error using ~(60)Co-γray as radiation resource to test space-ionizing-radiation-induced coloration in glasses,and the phenomenon is due to it that ~(60)Co-γray has a large penetration depth in the glass and the relaxation process of color centers is not considered.
