论文摘要
这项研究提出了对不锈钢128 nm闪烁光子的反射率的新实验确定。该实验发生在Fermilab的Tallbo Dewar设施中。数据是使用对落在其正面上的光子敏感的检测器获得的，但对落在其后面或侧面的光子不敏感。通过比较从照亮检测器前面的轨道的光子比率与可以通过模拟反射率变化的实验的轨迹的轨道的比率，从而确定了反射率的值。该实验发现的SA-240-304L不锈钢合金脱离了闪烁光子在高型露水中的反射率为r = 0.674 +/- 0.038。该实验对镜面反射和弥漫性反射之间的差异不敏感。
This investigation presents a new experimental determination of the reflectivity of 128 nm scintillation photons off stainless steel. The experiment took place in the TallBo dewar facility at Fermilab. The data were obtained using a detector that is sensitive to photons falling on its front face but is insensitive to photons falling on its back face or its sides. By comparing the ratio of photons per track from tracks that illuminate the front face of the detector to those that cross the back side with a simulation of the experiment where the reflectivity can be varied, a value of the reflectivity was determined. The reflectivity for the SA-240-304L stainless steel alloy off which the scintillation photons reflect in the TallBo dewar as found by this experiment is R = 0.674 +/- 0.038. The experiment is not sensitive to the differences between specular and diffuse reflections.
