摘要:

我们提出了第一次测量的电致发光响应的发射单电子在两相惰性气体检测器。在ZEPLIN-II实验的31天背景运行期间,在薄气体层中检测到液体氙中产生的单电离电子,ZEPLIN-II实验是用于WIMP暗物质搜索的两相氙探测器。的压力依赖性和单电子响应的幅度与以前的测量在氙中的电致发光产率一致。我们讨论了不同的光电离过程作为本工作中研究的单电子样本的可能原因。这一观察结果可能对未来大规模两相系统的设计和操作产生影响。

英文摘要:

We present the first measurements of the electroluminescence response to the emission of single electrons in a two-phase noble gas detector. Single ionization electrons generated in liquid xenon are detected in a thin gas layer during the 31-day background run of the ZEPLIN-II experiment, a two-phase xenon detector for WIMP dark matter searches. Both the pressure dependence and magnitude of the single-electron response are in agreement with previous measurements of electroluminescence yield in xenon. We discuss different photoionization processes as possible cause for the sample of single electrons studied in this work. This observation may have implications for the design and operation of future large-scale two-phase systems.
