摘要:

我们目前的数据表征的第一个分段,N型锗探测器,同位素富集到85% $^{76}$锗的性能。该探测器基于Ortec PT 6x 2设计,被称为SEGA(分段富集锗组件),由{ \sc Majorana}合作开发,作为无中微子双β衰变测量的可能原型。我们提出了一些一般特性(包括偏置电位,效率,漏电流,和积分串扰),这个探测器在其临时低温恒温器。我们还提出了一个分析的检测器的分辨率,并证明,所有,但两个部分有至少一个通道,达到{ \sc马约拉纳}分辨率目标低于4千电子伏的FWHM在2039千电子伏,所有通道均低于4.5千电子伏的FWHM。

英文摘要:

We present data characterizing the performance of the first segmented, N-type Ge detector, isotopically enriched to 85% $^{76}$Ge. This detector, based on the Ortec PT6x2 design and referred to as SEGA (Segmented, Enriched Germanium Assembly), was developed as a possible prototype for neutrinoless double beta-decay measurements by the {\sc Majorana} collaboration. We present some of the general characteristics (including bias potential, efficiency, leakage current, and integral cross-talk) for this detector in its temporary cryostat. We also present an analysis of the resolution of the detector, and demonstrate that for all but two segments there is at least one channel that reaches the {\sc Majorana} resolution goal below 4 keV FWHM at 2039 keV, and all channels are below 4.5 keV FWHM.
