基于高分段HPGe探测器的下一代伽马射线光谱仪正在使用最新的伽马射线跟踪技术，以显着提高效率和多普勒校正能力。通过使用脉冲形状分析（PSA），可以精确地重建活性物质内的单个相互作用位置，这反过来又需要对探测器响应的准确了解。我们开发了一个基于java的仿真软件包JASS，从物理约束和基本材料参数生成AGATA探测器的脉冲形状。为了验证仿真结果，采用了已知相互作用位置的重合扫描实验数据。所实现的位置分辨率，在几毫米的顺序，是在$伽马$射线跟踪阵列的要求。
Next-generation $ gamma$ -ray spectrometers based on highly segmented HPGe detectors are using the recent technique of $ gamma$ -ray tracking to significantly improve on efficiency and Doppler correction capabilities. A precise reconstruction of the individual interaction locations within the active material is possible through the use of pulse shape analysis (PSA) which, in turn, demands an accurate knowledge of the detector response. We developed JASS, a Java-based simulation software package to generate pulse shapes for the AGATA detectors from physics constraints and basic material parameters. For verifying the simulation experimental data from a coincidence scan with known interaction locations was used. The achieved position resolution, in the order of a few millimeters, is within the requirements of the $ gamma$ -ray tracking array.
