首次发现了托卡马克中存在迥异于通行粒子和香蕉粒子的第三种粒子, 这种粒子会由于漂移运动而摆脱磁场的约束. 研究了该类粒子在其速度空间上的类磁镜损失锥, 给出了这一损失锥的数学表达式, 分析了存在这一类粒子的物理成因, 模拟与数学分析的结果基本一致. 研究还发现, 回旋半径在二阶条件下带电粒子的轨道损失高于零阶情况, 且与装置参数密切相关.

A new kind of particle in tokamak, which is different from passing partilce and trapped particle, is found. This kind of particle can fly directly out of the boundary due to the drift motion. The loss cone in tokamak, which is composed of these particles, is studied. At the same time, the loss rates due to the banana orbit in different tokamaks are calculated.-
