提出了一种新的软件包，用于模拟分段真同轴高纯度锗探测器中电脉冲的形成。描述了探测器内部电场和加权电势以及载流子轨迹的计算。此外，还讨论了带宽限制和噪声的处理。介绍了从低温测试设施内运行的 18 倍分段探测器获得的模拟脉冲与测量脉冲的比较。
A new package to simulate the formation of electrical pulses in segmented true-coaxial high purity germanium detectors is presented. The computation of the electric field and weighting potentials inside the detector as well as of the trajectories of the charge carriers is described. In addition, the treatment of bandwidth limitations and noise are discussed. Comparison of simulated to measured pulses, obtained from an 18-fold segmented detector operated inside a cryogenic test facility, are presented.
