本文报道了一个经典的轨迹蒙特卡罗研究关于带电粒子的运动，该运动被引起漂移穿过磁场向人工结构的边界，从而产生空间周期性静电势。研究发现，对于所研究的系统，如果粒子与磁场平行运动的速度远大于粒子与回旋加速器运动的速度，则可以抑制粒子向边界的漂移。结果不依赖于粒子的电荷符号。讨论了束流或等离子体磁约束的可能含义。
A classical trajectory Monte Carlo study is reported regarding the motion of a charged particle that is caused to drift across a magnetic field toward an artificially structured boundary, which produces a spatially periodic electrostatic potential. It is found that, for the system studied, the drift toward the boundary is inhibited if the particle’s speed associated with motion parallel to the magnetic field is much larger than the particle’s speed associated with cyclotron motion. The results are not dependent on the particle’s sign of charge. Possible implications for magnetic confinement of beams or plasmas are discussed.
