摘要/Abstract

摘要： 采用能量一次吸收假设、等离子体平板模型和三维天线模型数值模拟离子回旋共振加热时带状双天线与等离子体的耦合过程,得到天线的辐射功率、等离子体的吸收功率密度分布随天线间距变化的关系.通过对比分析,得出结论:在一定实验条件下,当带状双天线同相馈电时,天线间距越小,离子回旋共振加热效果越好.

关键词: 离子回旋共振加热, 带状天线, 功率谱

Abstract: With a hypothesis that energy is completely absorbed by plasma in a plasma slab model and a three-dimensional antenna model,we numerically stimulate coupling of two strip antennas with plasma in ion cyclotron resonance heating.Antenna radiation power and power density distribution absorbed by plasma at different antenna distances are calculated.Through analyzing we draw a conclusion: For two strip antennas feed in phase at certain experimental parameters,the shorter the antenna distance is,the better ion cyclotron resonance heating is.

Key words: ion cyclotron resonance heating(ICRH), strip antenna, power spectrum
