论文摘要
HPGE检测器在$γ$ -ROAR-RAY在10 MeV左右的全能峰效率不容易通过实验方法访问。带有Geant4的蒙特卡洛模拟可以提供这些效率。 G4Horus是Horus HPGE-Detector数组的现成Geant4应用程序。用户可以配置模块化零件，以使其实验与模拟软件的最小知识和有限的时间承诺相匹配。在我们的情况下，以高精度了解和实施几何形状是最大的挑战。为了实施不同的目标室，我们将现有的CAD模型转换为使用Cadmesh的Geant4几何形状。我们还发现，对于某些较旧的HPGE探测器的实验效率和模拟效率之间的差异很大，可以通过在内核周围引入一个大死亡区域来进行修复。该项目是开源的，可从https://github.com/janmayer/g4horus获得，我们邀请所有人适应该项目或采用代码的其他项目。
The full-energy-peak efficiency of HPGe detectors at $γ$-ray energies around 10 MeV is not easily accessible with experimental methods. Monte-Carlo simulations with Geant4 can provide these efficiencies. G4Horus is a ready-to-use Geant4 application for the HORUS HPGe-detector array. Users can configure the modular parts to match their experiment with minimal knowledge of the simulation software and limited time commitment. In our case, knowing and implementing the geometry with high precision is the biggest challenge. To implement the different target chambers, we transform the existing CAD models to Geant4 geometry with CADMesh. We also found a large discrepancy between experimental and simulated efficiency for some older HPGe detectors, which could be remedied by introducing a large dead region around the inner core. This project is open source and available from https://github.com/janmayer/G4Horus We invite everyone to adapt the project or adopt parts of the code for other projects.
