在托卡马克中，通过观察电子漂移轨道的径向展宽，直接观察到测试电子的非经典扩散。发现这种增强的扩散与高极向模数的小尺度径向磁场波动之间有很强的相关性。从微撕裂模式的角度讨论了这些磁波动的来源。
Nonclassical diffusion of test electrons was directly observed in a tokamak by examination of the radial broadening of their drift orbits. A strong correlation between this enhanced diffusion and small-scale radial magnetic field fluctuations of high poloidal mode number was found. The origin of these magnetic fluctuations is discussed in terms of microtearing mode.
