Light reflectors are widely used to enhance scintillation light collection. Their enhancement level depends on the reflector’s reflectance at the scintillator’s emission wavelength. We report UV–Visible reflectance spectra, relative to BaSO₄, for several common reflectors. Also reported is their radiation hardness against an ionization dose up to 100 Mrad. The results of this investigation provide a reference for applications of these reflectors in a severe radiation environment.

普通光反射镜的紫外线可见反射率及其在电离剂量高达100 Mrad后的降解

光反射器被广泛用于增强闪烁光的收集。它们的增强程度取决于反射镜在闪烁体发射波长处的反射率。我们报告了几种常见反射镜相对于BaSO _4的紫外可见反射光谱。还报道了它们对高达100 Mrad的电离剂量的辐射硬度。研究的结果为这些反射镜在恶劣的辐射环境中的应用提供了参考。
