AI 中文摘要

在过去二十年中,采用蒙特卡洛碰撞的粒子网格模拟(PIC-MCC)为低温等离子体领域提供了关于射频放电中电子加热、鞘层与二次电子发射、条纹以及磁化等离子体不稳定性的绝大部分知识。然而,这些结果仍停留在论文中,以及仅其作者能够运行的代码中。JC-PIC 是一个免费的 Windows 程序:一个一维三速度(1D3V)静电 PIC-MCC 代码,配备并行 Fortran 引擎(OpenMP)和完整的图形界面。它围绕约一百个即用型用例的库构建,每个用例均有文档、参考文献和解释。其中约一半用例在原始条件下复现已发表的结果;其余用例则将代码与经典解析结果进行比较。本综述从物理角度介绍该程序、其配套书籍以及其中六个用例:从朗道阻尼到电子俘获的朗缪尔波、氩射频放电中的加热模式转变、电不对称效应、作为群落的弗兰克-赫兹实验、正柱条纹以及霍尔推进器的 ExB 漂移不稳定性。

英文摘要

Over the last twenty years, particle-in-cell simulations with Monte Carlo collisions (PIC-MCC) have given the low-temperature plasma community much of what it knows about electron heating in RF discharges, sheaths and secondary emission, striations, and the instabilities of magnetised plasmas. But these results remain in papers, and in codes that only their authors can run. JC-PIC is a free Windows program: a one-dimensional, three-velocity (1D3V) electrostatic PIC-MCC code with a parallel Fortran engine (OpenMP) and a complete graphical interface. It is built around a library of about one hundred ready-to-run cases, each documented, referenced and explained. About half of them reproduce a published result under the original conditions; the others compare the code with a classical analytical result. This overview presents the program, its companion book, and six of the cases from the physics point of view: Langmuir waves from Landau damping to electron trapping, the heating-mode transition in argon RF discharges, the electrical asymmetry effect, the Franck-Hertz experiment treated as a swarm, the striations of a positive column, and the ExB drift instability of Hall thrusters.
