论文摘要
聚二氟乙烯（PTFE），也称为Teflon，是一种用于液体氙气探测器的常见材料，因为其对Xenon的VUV闪烁光的高反射率很高。我们提出了PTFE的传输测量值，用于XENON闪烁光，并在175 nm的波长下峰值发射。具有不同厚度的PTFE圆盘在两个设置的光发射器前面安装。一个充满气态氙气，另一个用液体氙气。在室温下使用气态XENON设置执行的测量结果产生$λ= \ bigl的传输系数（350 {{}^{+60} _ {〜-0}}}} {} {} {} \，{\ Mathrm 50 \，{\ mathrm {（stat）}}} \ bigr）\，\ mathrm {μm} $。发现这与使用液体氙气设置进行的观测值一致。
Polytetrafluoroethylene (PTFE), also known as Teflon, is a common material used in the construction of liquid xenon detectors due to its high reflectivity for the VUV scintillation light of xenon. We present transmission measurements of PTFE for xenon scintillation light with peak emission at a wavelength of 175 nm. PTFE discs of different thicknesses are installed in front of a photosensor in two setups. One is filled with gaseous xenon, the other with liquid xenon. The measurements performed with the gaseous xenon setup at room temperature yield a transmission coefficient of $λ= \bigl(350{{}^{+60}_{~-0}}{}\,{\mathrm{(sys)}}\,\pm\, 50\,{\mathrm{(stat)}}\bigr)\,\mathrm{μm}$. This is found to be in agreement with the observations made using the liquid xenon setup.
