摘要

深入研究潘宁放电的物理机制, 研制了全三维高品质算法粒子模拟软件(PIC), 设计并添加了相应物理情景的蒙特卡罗碰撞模块(MCC), 并对电子、氢分子离子(H2+)、氢正离子(H+)、氢三正离子(H3+)同时进行了跟踪, 成功研制了全三维电磁PIC/MCC数值算法. 结合国内研究较热的潘宁放电模型, 对该算法进行模拟验证. 模拟结果显示: 采用有效的滤波算法能抑制电磁数值噪声, 电子能量呈麦克斯韦分布, 由于电子的径向漂移和加速导致离子源顶端H2+产量较大.

Abstract

In this article, we study the physical mechanism of the Penning discharge, develop a full three-dimensional particle simulation software of high-quality algorithm (PIC), design and add the corresponding physical scenario of Monte Carlo collisions (MCC) module, and track electron, hydrogen molecular ion (H2+), hydrogen positive ion (H+), and tri-n-hydrogen ion (H3+) at the same time, and successfully develop a full three-dimensional electromagnetic PIC/MCC numerical algorithm. Combined with the Penning discharge model extensively studied in china, the algorithm is verified through simulation. The simulation results show that the use of effective filtering algorithm can suppress the electromagnetic numerical noise. Electron energy is of Maxwell distribution. Due to the radial drift and accelerate of electrons, the H2+ yield is larger at the top of the ion source.
