HL-1M等离子体中ECW传播和吸收的数值分析

计算了频率在电子回旋频率附近O波和X波在HL－1M等离子体中的传播轨迹和吸收系数。研究了等离子体温度、密度和共振层位置等参数及波的入射对波迹和功率沉积分布的影响。结果表明，O波和X波能有效地被等离子体吸收，其吸收具有定域性，波的单次吸收系数较高，功率的沉积强烈地依赖等离子体参数。

NUMERICAL ANALYSIS OF ECW PROPAGATION AND ABSORPTION IN THE HL-1M PLASMA

Wave traces and absorption coefficients of O-mode and X-mode waves near the electron cyclotron frequency were computed in the HL-1M plasma.Influences of the incident angle for wave and plasma parameters such as temperature,density and location of resonance layer on wave traces and power deposition distribution were studied.Results showed that both O-mode and X-mode waves can be effectively absorbed by the plasma,the absorbability of the plasma is highly localized,the single absorbance is high,and the power deposition strongly relies on the plasma parameters.
