摘要: 用蒙特卡罗方法,采用三维计算模型,模拟了阴极区内电子的运动。得出了电子分布函数以及宏观参数,包括电子平均能量、汤生电离系数、增殖系数等,并与一维结果进行了比较。结果表明,角向散射明显地影响着电子分布函数和主要参数。

Abstract: In this paper, electron movement in the cathode fall region of a glow discharge in Argon has been simulated using the three dimensional Monte Carlo method, which has taken advantage of a null-collision technique. The electron distribution functions and the macroscopic electron parameters including the mean electron energy, the mutiplication coefficient and the Townsend inoizion coefficient are given and compared with those obtained with the one dimensional computer model. The results have shown that the angular scattering has significantly affected the electron behavour.

Key words: glow discharge, null-collision technique, Monte Carlo simulation
