论文摘要
构建了P型高纯族检测器中的Li-Diffuse层的非活性层的模型,以描述电荷载体的运输并计算其中的电荷收集效率。该模型用于计算罕见事件物理实验中使用的P型点接触式锗检测器的电荷收集效率,并在另一个P型半平面锗检测器中进行了验证。计算出的电荷收集效率曲线与两个检测器的测量非常一致。根据模型讨论了LI掺杂过程对电荷收集效率的影响。 This model can be easily extended to other P-type germanium detectors, for instance, the P-type broad-energy Ge detector, and the P-type inverted-coaxial point-contact detector.
A model of the Li-diffused inactive layer in P-type high purity germanium detectors is built to describe the transportation of charge carriers and calculate the charge collection efficiency therein. The model is applied to calculate charge collection efficiency of a P-type point-contact germanium detector used in rare event physics experiments and validated in another P-type semi-planar germanium detector. The calculated charge collection efficiency curves are well consistent with measurements for both detectors. Effects of the Li doping processes on the charge collection efficiency are discussed based on the model. This model can be easily extended to other P-type germanium detectors, for instance, the P-type broad-energy Ge detector, and the P-type inverted-coaxial point-contact detector.
