论文摘要
液态贵族元素产生的真空紫外线（VUV）闪烁光是为了充分利用利用这些媒体的检测器中可用的时机，拓扑和量热信息，这是一个核心挑战。在本文中，我们表征了一种新型的，无窗的无定形硒基探测器，对VUV光的敏感性直接敏感。我们在这里介绍用于在低运输电场（2.7-5.2 V/$ $ $ M）和跨温度（77K-290K）的制造和实验设置。这项工作表明，第一批原本设备无窗的无定形硒在低温条件下是可靠的，在低温温度下对VUV光的反应，并保留了氩气纯度。这些发现激发了对非晶硒设备的持续探索，以同时检测闪烁的光和电离电荷。
Detection of the vacuum ultraviolet (VUV) scintillation light produced by liquid noble elements is a central challenge in order to fully exploit the available timing, topological, and calorimetric information in detectors leveraging these media. In this paper, we characterize a novel, windowless amorphous selenium based photodetector with direct sensitivity to VUV light. We present here the manufacturing and experimental setup used to operate this detector at low transport electric fields (2.7-5.2 V/$μ$m) and across a wide range of temperatures (77K-290K). This work shows that the first proof-of-principle device windowless amorphous selenium is robust under cryogenic conditions, responsive to VUV light at cryogenic temperatures, and preserves argon purity. These findings motivate a continued exploration of amorphous selenium devices for simultaneous detection of scintillation light and ionization charge in noble element detectors.
