FPPAC88: A two-dimensional multispecies nonlinear Fokker-Planck package

Abstract
FPPAC88 solves the complete nonlinear multispecies Fokker-Planck collision operator for a plasma in two-dimensional velocity space. The operator is expressed in terms of spherical coordinates (speed and pitch angle) under the assumption of azimuthal symmetry. Provision is made for additional physics contributions (e.g. rf heating, electric field acceleration). The charges species, referred to as general species, are assumed to be in the presence of an arbitrary number of fixed Maxwellian spec...

Nature of problem
The complete nonlinear multispecies Fokker-Planck collision operator for a plasma in two-dimensional velocity space is solved. The operator is expressed in terms of spherical coordinates (v=speed, theta=angle between velocity and magnetic field directions, phi=azimuthal angle) under the assumption of azimuthal symmetry. Provision is made for additional physics contributions.

摘要
FPPAC88用于求解二维速度空间中等离子体的完整非线性多物种福克-普朗克碰撞算子（Fokker-Planck collision operator）。该程序在方位对称性（azimuthal symmetry）假设下，以球坐标系（spherical coordinates，包含速率与俯仰角）形式表达该碰撞算子，并预留了额外物理效应的扩展接口（例如射频加热（rf heating）、电场加速（electric field acceleration））。原文提及的带电粒子种类（原文笔误作charges species，标准术语为charged species，亦称通用粒子种类），被假设处于任意数量的固定麦克斯韦分布（Maxwellian）粒子环境中……

问题本质
本程序用于求解二维速度空间中等离子体的完整非线性多物种福克-普朗克碰撞算子。该算子在方位对称性假设下，以球坐标系（v=速率，θ=速度与磁场方向夹角，φ=方位角）形式表达，并预留了额外物理效应的扩展接口。
