对圆形截面托卡马克等离子体中存在磁岛时的低混杂波电流驱动进行了数值研究。磁岛的出现被认为是一种扰动，其特征在于谐振表面附近的扰动磁通量。通过考虑扰动磁场的低杂波模拟代码，波的传播，功率沉积，和电流驱动的研究使用典型的实验先进超导托卡马克（EAST）的L-和H-模式放电参数。仿真结果表明，磁岛的存在对电磁波的传播、功率沉积和电流驱动都有显著的影响。由于H模基座的存在，EAST H模放电中磁岛对LHCD的影响要比L模放电中的大。
The lower hybrid wave current drive (LHCD) in the presence of magnetic islands in Tokamak plasma with the circular cross section is studied numerically. The emergence of magnetic island is considered as a perturbation characterized by the perturbed magnetic flux near the resonant surface. By taking the perturbed magnetic field into account in the lower hybrid simulation code, the wave propagation, power deposition, and current drive are investigated using typical Experimental Advanced Superconductor Tokamak (EAST) L- and H-modes discharge parameters. The simulation results show that the wave propagation, power deposition, and current drive are significantly affected by the existence of magnetic island. Due to the H-mode pedestal, the effect of magnetic islands on the LHCD in EAST H-mode discharge is more significant than that in the L-mode discharge.
