论文摘要
第一次,小型双相(液/气)氙时间投影室配备了顶部的硅光电层流阵列,用于光线和电荷读数。在这里,我们将详细描述该仪器,以及数据处理和事件位置重建算法。我们在水平面上获得了〜1.5 mm的空间分辨率。为了表征检测器性能,我们显示了内部$^{83 \ text {m}} $ kr和$^{37} $ ar源的校准数据,我们详细介绍了后者的生产以及其在系统中的引入。我们最终将观察到的光和电荷产生与2.82 KEV的电子后坐力和基于NEST V2.0的预测进行了比较。
For the first time, a small dual-phase (liquid/gas) xenon time projection chamber was equipped with a top array of silicon photomultipliers for light and charge readout. Here we describe the instrument in detail, as well as the data processing and the event position reconstruction algorithms. We obtain a spatial resolution of ~1.5 mm in the horizontal plane. To characterise the detector performance, we show calibration data with internal $^{83\text{m}}$Kr and $^{37}$Ar sources, and we detail the production of the latter as well as its introduction into the system. We finally compare the observed light and charge yields down to electronic recoil energies of 2.82 keV to predictions based on NEST v2.0.
