对来自三个不同制造商（Suprasil、Lithosil和Corning）的最高光学等级的熔融石英样品进行了辐射硬度测试。为了模拟未来PANDA实验的整个寿命期内预期的累积辐射损伤，用质子辐照样品。光学性质的变化是本研究的主要焦点。使用商业分光光度计研究了从UV到可见光的宽波长带上的光透射。此外，使用干涉仪研究了抛光表面的变化。在获得的精度范围内，未发现透射率和表面质量变化的证据。
Radiation hardness tests have been carried out on fused silica samples of the highest optical grade from three different manufacturers (Suprasil, Lithosil and Corning). The samples were irradiated with protons in order to emulate the expected accumulated radiation damage over the entire life span of the future PANDA experiment. Changes in optical properties were the primary focus of this study. The optical transmission over a broad wavelength band ranging from UV to visible light was investigated using a commercial spectrophotometer. In addition, changes of the polished surface were studied using an interferometer. No evidence for changes in transmission and surface quality was found within the obtained precision.
