摘要

在把离子伯恩斯坦波处理成对快阿尔芬波的响应下

导出了点火托卡马克等离子体的离子回旋混合共振的二阶方程.数值求解这个二阶方程得到了快波电场E

的结构和在共振区快波的转换和反射等.结果与高阶方程的计算很好地一致.计算还得到

只有在弱阻尼的情况下

α粒子吸收的功率才是重要的.

Abstract

By treating the heavily-damped ion Bernstein wave as a driven response to the fast Alfven wave

we have derived a second-order mode-conversion equation describing the wave-plasma interaction in ion cyclotron resonance heating in three-ion species plasma.The structure of fast wave electron field E

is derived from this numerically analytical solution of this equation and the mode-conversion on the domain of resonance

and reflection is also obtained.The results are in good agreement with those obtained from higher order equations.The hot alpha particle power absorption is important only when the damping is weak.
