栅极电离室(GIC)的栅极用于消除阳极脉冲幅度对电离初始位置和取向的依赖。传统的电网生产方法需要繁琐的工艺和先进的仪器。提出了一种粘结不锈钢编织网(SSWWM)栅极的制作方法。与传统的栅极电极相比，SSWWM栅极具有制造简单、成本低、机械强度高等优点。在241Am源(约5.486 MeV)上测试了40目、60目和80目SSWWM网格以及用传统绕线方法实现的正交网格的能量分辨率。结果表明，SSWWM和正交网格的最佳能量分辨率约为47keV半高全宽。40目和60目SSWWM栅格的最优能量分辨率是相当的，但对应于能量分辨率平台的初始工作电压不同，这主要是由于SSWWM栅格的不同几何参数对电子透过率的影响。利用模拟程序对SSWWM栅极的电子透过率进行了研究。模拟结果与实验结果吻合较好，表明该模拟程序可作为SSWWM网格几何参数选择的参考。
Abstract The grid electrode of the grid ionization chamber (GIC) is devoted to eliminating the dependence of the anode pulse amplitude on the initial position and orientation of the ionization. The traditional methods of grid production require cumbersome processes and advanced instruments. In this paper, a bonded stainless steel woven wire mesh (SSWWM) grid electrode manufacturing method is proposed. Compared with the traditional grid electrode, the SSWWM grid features the advantages of simple fabrication, low cost, and high mechanical strength. The energy resolutions of the 40-mesh, 60-mesh and 80-mesh SSWWM grids and orthogonal mesh grid realized by the traditional wire winding method were tested using an 241 Am source (around 5.486 MeV). The results show that the optimum energy resolution of the SSWWM and orthogonal mesh grids is approximately 47 keV full width at half-maximum (FWHM). The optimal energy resolutions of the 40-mesh and 60-mesh SSWWM grids are comparable, but the initial operating voltages corresponding to the energy resolution plateau are different, mainly because of the effect of the different geometric parameters of the SSWWM grid on the electron transmittance. A simulation program was used to study the electron transmittance of the SSWWM grid. The simulation results are in agreement with the experimental results, indicating that the simulation program can be used as a reference for the selection of the geometric parameters of the SSWWM grid.
