摘要:

采用等离子体平板模型和三维天线模型数值模拟了托卡马克中ICRH天线与等离子体的耦合过程, 模拟结果表明在其它实验条件相同的条件下,与反对称电流和馈线端长度短的天线相比,对称电流分布和馈线端长度长的发射天线可获得更有效的功率耦合。

关键词: 平板模型, 三维天线模型, 离子回旋共振加热, 功率谱, 天线馈线端长度

Abstract:

The coupling of the ICRF antenna to the plasma in tokamak is studied by using a plasma slab model and a three-dimensional antenna model. The simulation results show that under the same conditions, the antenna of symmetric current distribution and a long feeder may have more effective power coupling than the antenna of antisymmetric current distribution and a short feeder.

Key words: Slab model, Three-dimensional antenna model, Ion cyclotron resonance heating (ICRH), Power spectrum, Length of the antenna feeder
