论文摘要
高纯净锗检测器中电荷载体漂移引起的信号的时间分析提供了有关事件拓扑的信息。在一个典型的事件中生产数百万个电荷载体。它们的初始分布，随机扩散和库仑自我抑制会影响信号的时间结构。我们介绍了这些效果的全面研究，并评估了它们对事件歧视能力的影响，这将用于三种几何形状，这些几何形状将用于中微子双β衰变的传奇实验。
The time analysis of the signal induced by the drift of charge carriers in high purity germanium detectors provides information on the event topology. Millions of charge carriers are produced in a typical event. Their initial distribution, stochastic diffusion and Coulomb self-repulsion affect the time structure of the signal. We present a comprehensive study of these effects and evaluate their impact on the event discrimination capabilities for the three geometries which will be used in the Legend experiment for neutrinoless double-beta decay.
