We study the optical properties of glass exposed to ionizing radiation as it occurs in the space environment. Twenty-four glass types have been considered, both space-qualified and not space-qualified. Seventy-two samples (3 for each glass type) have been irradiated to simulate total doses of 10 and 30 krad imposed by a proton beam at KVI-Centre of Advanced Radiation Technology (Groeningen). Combining information concerning stopping power and proton fluence, the time required to reproduce any given total dose in a 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 of 200 to 1100 nm. Indications that systematical issues depend on the dopant or composition are found and described. Our work aims at extending the existing list of space-compliant glasses in terms of radiation damage.

辐射损伤对玻璃光学性能的影响

我们研究了在空间环境中发生电离辐射的玻璃的光学特性。已经考虑了二十四种玻璃类型，既有空间限定的，也有空间限定的。在高级辐射技术（格罗宁根）的KVI中心，已对72个样品（每种玻璃为3个）进行了辐照，以模拟质子束施加的总剂量10和30 krad。结合有关停止功率和质子注量的信息，可以很容易地获得在真实环境中再现任何给定总剂量所需的时间。对每个样品在辐照之前和之后都测量了光学性质，例如光谱透射和光散射。在200至1100 nm的波长范围内已表征了透射率。发现并描述了系统性问题取决于掺杂剂或组成的迹象。我们的工作旨在就辐射损伤扩大现有的符合太空要求的眼镜清单。
