Abstract

Abstract:

The power deposition profile of the lower hybrid wave (LHW) and the distribution of the current driven byLHWunder the local synergistic interaction ofLHWand ion Bernsteinwave (IBW) have been studied using advanced ray-tracing and 2-DFokker-Planck numerical code. The numerical simulation results showthatthe LHWpower deposition profile and the driven current distribution are modified due to the interaction of IBWwithLHW, IBWabsorption by elec- trons via electron Laudau damping (ELD) around the maximums ofn+offering a possible mechanismof plasma heating, and the efficiency of LHCD is improved.

Key words: LHW, IBW, Synergy, Numeric simulation, ELD

摘要：

利用改进的二维Fokker-Planck方程和低杂波射线轨迹程序研究了在低杂波和离子伯恩斯坦波协同作用下低杂波的功率沉积分布、驱动电流分布。数值结果显示在两波协同作用下低杂波驱动非感应电流的效率得到了很大的改善。
