论文摘要
我们已经结合了两种低阈值检测器技术，以开发出大型的低阈值检测器系统，该系统同时测量蓝宝石检测器中的Athermal Phonons，而相邻的硅高压检测器可检测蓝宝石检测器的闪烁光。由于其闪烁光收益率差异，该检测器系统可以在电子和核事件之间划分事件歧视。尽管较小的探测器早些时候已经证明了具有同时声子和光检测的系统，但我们的系统旨在为有限的闪烁光提供具有高扩增的较大检测器质量。未来的工作将通过具有高度反射性检测器壳体和自定义的声子掩码设计来最大程度地提高光收集效率的数量级提高顺序，从而最大程度地收集了硅高压检测器的光收集。
We have combined two low-threshold detector technologies to develop a large-mass, low-threshold detector system that simultaneously measures the athermal phonons in a sapphire detector while an adjacent silicon high-voltage detector detects the scintillation light from the sapphire detector. This detector system could provide event-by-event discrimination between electron and nuclear events due to the difference in their scintillation light yield. While such systems with simultaneous phonon and light detection have been demonstrated earlier with smaller detectors, our system is designed to provide a large detector mass with high amplification for the limited scintillation light. Future work will focus on at least an order of magnitude improvement in the light collection efficiency by having a highly reflective detector housing and custom phonon mask design to maximize light collection by the silicon high-voltage detector.
