空间电离辐照主要由能量连续变化的粒子组成,绝大多数粒子穿透能力小,因此,空间电离辐照对玻璃的着色损伤必然随深度而呈现一种复杂的变化,针对这一现象,并且考虑到玻璃中色心的弛豫消失,本工作建立了一种适用于玻璃空间电离辐照着色损伤动力学研究的方法.以K9-HL玻璃为研究对象,利用空间电离辐照作用在玻璃中随深度变化的Monte Carlo模拟结果,研究了该玻璃在轨(近地点350 km,远地点425 km,轨道倾角51.6°)电离辐照着色损伤过程,讨论了航天器用玻璃抗辐照性能考核方法,分析了玻璃空间电离辐照着色损伤的深度分布,提出了航天器用玻璃材料抗电离辐照损伤加固的关键点.此外,对不同石英玻璃防电离辐照层保护的K9-HL玻璃在轨光学性能做了研究.
