论文摘要
在本文中，我们研究了环形公理对称几何形状下强磁场下的带电粒子动力学。使用精确和数值解的调制傅立叶膨胀，得出了环形几何形状中精确溶液的长期漂移运动，并在长时间尺度上提供了大型修改的鲍里斯算法的误差分析。数值实验说明了理论结果。
In this paper, we study the charged-particle dynamics under strong magnetic field in a toroidal axi-symmetric geometry. Using modulated Fourier expansions of the exact and numerical solutions, the long-term drift motion of the exact solution in toroidal geometry is derived and the error analysis of the large-stepsize modified Boris algorithm over long time scales is provided. Numerical experiments illustrate the theoretical results.
