论文摘要
我们研究暴露于电离辐射的玻璃的光学性质，因为它在太空环境中发生。已经考虑了24种玻璃类型，包括空间合格和不含空间的玻璃类型。已经辐照了72个样品（每种玻璃类型3），以模拟总剂量10克拉德和30克拉德，由质子束在高级辐射技术（Groeningen）的KVI-中心施加。将有关停止功率和质子通量的信息结合在一起，可以轻松地在真实环境中重现任何给定的总剂量所需的时间。在每个样品的照射之前和之后，已经测量了光谱传播和光散射等光学特性。在200 nm-1100 nm的波长范围内表征了传输。发现并描述了系统性问题取决于掺杂剂或组成的迹象。这项工作旨在扩展现有的符合空间玻璃的列表，以辐射损坏。
We study the optical properties of glass exposed to ionizing radiation, as it occurs in the space environment. 24 glass types have been considered, both space qualified and not space qualified. 72 samples (3 for each glass type) have been irradiated to simulate a total dose of 10krad and 30krad, imposed by a proton beam at KVI-Centre of Advanced Radiation Technology (Groeningen). Combining the information about stopping power and proton fluence, the time required to reproduce any given total dose in the real environment can be easily obtained. The optical properties, such as spectral transmission and light scattering have been measured before and after irradiation for each sample. Transmission has been characterized within the wavelength range 200 nm-1100 nm. Indications that systematical issues depend on the dopant or composition are found and described. This work aims at extending the existing list of space-compliant glasses in terms of radiation damage.
