新一代气体探测器的三维仿真

3D Simulation of New Generation Gas Detectors

S. Mukhopadhyay, N. Majumdar

摘要:

由于电场的非平凡性质和同时存在的几个长度尺度,新一代气体检测器的模拟变得复杂。然而,静电场的计算是极其重要的,因为气体体积中的流光和穿过电介质表面的流光已知会对微图案气体检测器(MPGD)造成严重损害,并且是限制其增益的主要因素。在本文中,我们提出了一个接近精确的边界元法(neBEM)求解器,克服了大多数的限制有限元软件包,能够产生准确的结果。

英文摘要:

Simulation of new generation gas detectors is rendered complicated due to the non-trivial nature of the electric field and simultaneous presence of several length-scales. Computation of the electrostatic field, however, is extremely important since streamers in gas volume and streamers across the dielectric surfaces are known to cause serious damage to Micro Pattern Gas Detectors (MPGD)and are the main factors in limiting their gain. In this paper, we present the use of a nearly exact Boundary Element Method (neBEM) solver that overcomes most of the limitations of FEM packages and is capable of producing accurate results.
