摘要:

\textsc{Majorana} \textsc{Demonstrator}项目的目标是在$^{76}\mathrm{Ge}$中寻找0 $νββ$衰变。在$νββ$的所有候选同位素中,$^{76}\mathrm{Ge}$具有一些最有利的特性。锗探测器是一种成熟的技术,在寻找0 $νββ$时,高纯度锗晶体同时用作源和探测器。此外,p型锗探测器提供了出色的能量分辨率,特别设计的点接触几何形状允许灵敏的脉冲形状辨别。本文将总结\textsc{Majorana}与ORTEC $^{\circledR}$生产的富锗探测器合作的经验。将描述从生产到表征和集成到\textsc{Majorana}安装结构中的过程。将给出所有富集锗探测器的性能的总结。

英文摘要:

The goal of the \textsc{Majorana} \textsc{Demonstrator} project is to search for 0$νββ$ decay in $^{76}\mathrm{Ge}$. Of all candidate isotopes for 0$νββ$, $^{76}\mathrm{Ge}$ has some of the most favorable characteristics. Germanium detectors are a well established technology, and in searches for 0$νββ$, the high purity germanium crystal acts simultaneously as source and detector. Furthermore, p-type germanium detectors provide excellent energy resolution and a specially designed point contact geometry allows for sensitive pulse shape discrimination. This paper will summarize the experiences the \textsc{Majorana} collaboration made with enriched germanium detectors manufactured by ORTEC$^{\circledR}$. The process from production, to characterization and integration in \textsc{Majorana} mounting structure will be described. A summary of the performance of all enriched germanium detectors will be given.
