对磁岛中由新经典撕裂模引起的电子回旋电流驱动进行了数值模拟。用蒙特-卡罗方法模拟了库仑碰撞和EC波准线性扩散对电子漂移轨道的影响。假设EC谐振区位于O点周围，并定位在环形方向上。驱动电流被很好地限制在包括EC谐振区的螺旋磁通管中。驱动电流通道在真实的空间中看起来像“蛇”。作为在ne = 3 × 1019 m−3和Te = 10 keV的等离子体中具有10 MW的ECCD的结果，电流驱动效率比没有磁岛的轴对称等离子体高约1.6倍。随着EC波功率的增加，驱动电流分布趋于在O点附近达到峰值。
Electron cyclotron current drive (ECCD) has been numerically simulated in magnetic islands caused by neo-classical tearing modes. The electron drift orbits are tracked with the Coulomb collisions and the quasi-linear diffusion by EC waves, which are simulated by the Monte-Carlo method. The EC resonance region is assumed to be located around the O-point and localized in the toroidal direction. The driven current is well confined in the helical flux tube which includes the EC resonance region. The driven current channel looks like a ‘snake’ in real space. As the results of the ECCD with 10 MW in a plasma with ne = 3 × 1019 m−3 and Te = 10 keV, the current drive efficiency is about 1.6 times higher than that of an axi-symmetric plasma with no magnetic island. The driven current profile tends to peak around the O-point with increasing EC wave power.
