利用由全波方法求解得到的离子回旋频率范围内快波在等离子体中激发产生的电场,采用Kennel和Engelman给出的扩散系数表达式,通过数值计算得到了离子回旋频率范围内快波在速度空间下的准线性扩散系数.利用其结果求解Fokker-planck方程,为进一步研究离子回旋频率范围内的快波在Tokamak等离子体中的电流驱动提供了理论基础.

Based on the wave fields evaluated by full wave method, the various components of quasilinear diffusion coefficient in spherical velocity coordinates are obtained by numerically resolving. The quasilinear diffusion coefficient of Fokker - planck equation is presented for investigating fast wave current drive in the ion cyclotron range of frequencies, and the results will be used to solve bounce -averaged quasilinear Fokker- Planck equa...
