论文摘要
基于液体的探测器广泛用于粒子和核物理实验中。由于在诸如Geant4之类的检测器模拟中构造几何形状的固定方式，通常很难描述探测器中液体的不均匀性。我们提出了一种基于GDML和镶嵌检测器描述的方法，以共享计算流体动力学（CFD）仿真软件和检测器仿真软件之间的检测器几何信息。该方法使研究液体流量和不均匀性对液体基探测器的某些关键性能的影响，例如事件顶点重建分辨率。这也将有助于探测器设计和性能优化。
The liquid-based detectors are widely used in particle and nuclear physics experiments. Due to the fixed way of constructing geometry in detector simulation such as Geant4, it is usually difficult to describe the non-uniformity of liquid in detectors. We propose a method based on GDML and tessellated detector description to share the detector geometry information between Computational Fluid Dynamics (CFD) simulation software and detector simulation software. The method makes it possible to study the impact of liquid flow and non-uniformity on some key performance of the liquid-based detectors, such as event vertex reconstruction resolution. It will also be helpful in detector design and performance optimization.
