| 摘 要： | 本文通过求解Fokker-Planck方程和射线追踪技术,详细研究了托卡马克等离子体中,低混杂波电流驱动(LHCD)与电子回旋波电流驱动(ECCD)的协同作用,结果表明,这种协同作用有利于用EC波驱动电流;捕获电子效应对电流驱动有一定影响,特别是O波弱场注入时,影响更为明显;驱动的电流对平衡磁场很敏感,磁场的大小也影响驱动电流的剖面。

| Abstract: | The synergetic effect of lower hybrid current drive(LHCD)and electron cyclotron current drive(ECCD)in tokamak plasmas is investigated by solving the two-dimensional Fokker-Planck equation and utilizing the technique of ray tracing. The effect of trapped particles on the generated current is taken into account. Numerical calculations have been carried out for the case of perpendicular injection of electron cyclotron waves into plasmas. The results indicate that the current generated by LHCD is greatly enhanced by the synergetic effect. Meanwhile, the generated current is strongly affected by the trapped particles, especially when the EC-wave is injected from the low-field side. |
