摘要建立了一种新的Frisch栅极电离室，以探索Frisch栅极的合适选择。用$$^{241}$$对网格几何形状和探测器性能之间的关系进行了详细研究。241.AM消息来源。本文描述并比较了不同网格参数的平行线和网格式电离室的能量分辨率。根据目前可用的数据，提供了一些关于网格选择的具体建议。为了获得最佳的能量分辨率，电离室的工作电压必须分别满足具有不同几何形状和参数的栅极上的最小电子收集条件。由于目前还没有适用于这两种网格的理论，我们设计了一个结合COMSOL和GARFIELD++程序的仔细的模拟程序，以寻找网格上最小的电子收集条件。仿真结果与实验数据吻合较好，表明该仿真方法成功地预测了采用网格栅或平行线栅作为屏蔽电极时合适的电压设置。

AbstractA new Frisch-grid ionization chamber has been built to explore the appropriate choice of Frisch-grid. Detailed studies of the relationship between grid geometries and detector performance have been performed with an $$^{241}$$. 241. Am source. This paper describes and compares the energy resolution of ionization chambers with parallel-wire and mesh grids of different grid parameters. Some specific recommendations for grid selection are provided based on the data currently available. To obtain optimal energy resolution, the operating voltage of the chamber must satisfy the condition of minimum electron collection on the grid with distinct geometries and parameters, respectively. Since there is no established theory applicable to both types of grids, we have devised a careful simulation procedure incorporating the COMSOL and Garfield++ codes to search for the conditions of the minimum electron collection on the grid. The simulation results fit the experimental data well, suggesting that this simulation method successfully predicts the suitable voltage setting when using a mesh grid or parallel wires grid as the shielding electrode.
