摘要：

无中微子双β衰变搜索在确定中微子的性质、轻子破坏过程的存在和有效马约拉纳中微子质量方面起着重要作用。马约拉纳合作组织建议组装一个HPGe探测器阵列，以寻找Ge-76中的无中微子双β衰变。我们所提出的方法使用了完善的技术，寻找无中微子双β衰变在高纯度锗二极管辐射探测器，发挥源和探测器的作用。该技术的增强与最近的改进，在信号处理和检测器的设计，并在控制内在和外部背景的进步。最初，Majorana的目标是建造一个包含60公斤锗探测器的原型模块，以展示未来1吨实验的潜力。将介绍这一原型演示模块的设计和潜在范围。本文还将讨论探测器优化和低背景要求，如材料纯度，背景抑制，并识别稀有背景所需的达到灵敏度目标的马约拉纳实验。

英文摘要：

Neutrinoless double-beta decay searches play a major role in determining the nature of neutrinos, the existence of a lepton violating process, and the effective Majorana neutrino mass. The Majorana Collaboration proposes to assemble an array of HPGe detectors to search for neutrinoless double-beta decay in Ge-76. Our proposed method uses the well-established technique of searching for neutrinoless double-beta decay in high purity Ge-diode radiation detectors that play both roles of source and detector. The technique is augmented with recent improvements in signal processing and detector design, and advances in controlling intrinsic and external backgrounds. Initially, Majorana aims to construct a prototype module containing 60 kg of Ge detectors to demonstrate the potential of a future 1-tonne experiment. The design and potential reach of this prototype Demonstrator module will be presented. This paper will also discuss detector optimization and low-background requirements, such as material purity, background rejection, and identification of rare backgrounds required to reach the sensitivity goals of the Majorana experiment.
