摘要 采用等离子体分层模型,利用WKB近似研究了离子回旋共振加热(ICRH)天线发射谱n‖对离子回旋波在托卡马克等离子体的表面功率反射系数、吸收衰减的影响,数值模拟了不同天线发射谱n‖条件下快波少数离子加热的效果。模拟结果表明,当其它实验参数一定时,ICRH天线发射合适的n‖能提高天线与等离子体的耦合效率,增强少数离子加热的效果。 The relation of the power reflection coefficient in tokamak plasma surface and absorption attenuation of the ion cyclotron wave to the emission spectrum n││ of ICRH antenna is studied by using a stratified plasma slab and the WKB approximation. The effect of fast wave minority ion heating in different emission spectrum conditions of ICRH antenna is numerical calculated. The simulation results show that under the same conditions, the coupling efficiency of the antenna with the plasma and the effect of fast wave minority ions heating can be improved and enhanced by suitable spectrum n││ of ICRH antenna.
