Collisionless particle dynamics in a helical magnetic mirror is investigated by methods of the Hamilton dynamics. In the limit of small Larmor radius, the Hamiltonian is fully integrable and particle trajectories can be divided into three types, differing in the direction of the drift velocity. The structure of the trajectories of resonant particles and the width of the resonance are studied. The influence of weak axi-symmetrical corrugation on the particle dynamics and efficiency of plasma flow suppression through a helical mirror are discussed.

带有螺旋波纹的捕集区中的无碰撞粒子动力学

利用汉密尔顿动力学方法研究了螺旋磁镜中的无碰撞粒子动力学。在较小的拉莫尔半径的范围内，哈密顿量是完全可积的，并且粒子轨迹可以分为三种类型，即漂移速度的方向不同。研究了共振粒子的轨迹结构和共振宽度。讨论了弱轴对称波纹对颗粒动力学的影响以及通过螺旋镜抑制等离子体流的效率。
