研究了两种类型的Heraeus Suprasil合成熔融石英在暴露于电离辐射后作为DIRC辐射器使用时的光学透射率的退化。这些研究导致了缺陷机制的发现，这是众所周知的紫外线激光照射也存在电离辐射。现有的缺陷模型预测的光学退化对间隙氢的依赖性，可以得到验证。这导致对辐射损伤过程的更好理解，并允许根据实验要求，特别是在辐射负荷方面，指定合成熔融石英的组成。
The degradation of optical transmission of two types of Heraeus Suprasil synthetic fused silica after exposure to ionising radiation was investigated with regard to usage as a DIRC radiator. These studies led to the discovery of defect mechanisms that are well known for UV laser irradiation also being present for ionising radiation. The dependence of the optical degradation on interstitial hydrogen, as predicted by existing defect models, could be verified. This leads to an improved understanding of the radiation damage processes and allows to specify the composition of synthetic fused silica according to experimental requirements especially in terms of radiation load.
