利用Garfield程序模拟Micromegas探测器增益和位置分辨特性(英文)

利用Garfield气体探测器模拟程序模拟了不同条件下Micromegas探测器的增益和位置分辨特性.通过对模拟结果的分析,得出提高探测器位置分辨和增益的有效途径.该工作不仅可以优化气体探测器结构设计,缩短实验周期,而且还能极大程度的节约经费.

Simulation of micromegas detector by garfield program

In this paper, a batch file which describes the detailed structure and the corresponding physical process of Micro-Mesh Gaseous Structure (Micromegas) detector, the macro commands and the control structures based on the Garfield program has been developed. And using the Garfield program controlled by this batch file, the detector's gain and spatial resolution have been investigated under different conditions. These results obtained by the simulation program not only exhibit the influences of the mesh and drift voltage, the mixture gas proportion, the distance between the mesh cathode and the printed circuit board readout anode, and the Lines Per Inch of the mesh cathode on the gain and spatial resolution of the detector, but also are very important to optimize the design, shorten the experimental period, and save cost during the detector development. Additionally, they also indicate that the Garfield program is a powerful tool for the Micromegas detector design and optimization.
