E. V. Sysoeva, F. da Silva, E. Z. Gusakov, S. Heuraux, A. Yu. Popov

摘要:

本文提出了两种非均匀边缘等离子体层中普通模传输的解析模型。简单的解析表达式扩散的角度和空间的光束宽度的变化,并比较来自不同的湍流k-光谱和等离子体条件的2D麦克斯韦方程求解器的时间平均结果。利用这两种方法对ITER ECRH实验中实际湍流边缘参数下微波束的强空间展宽进行了预测。

英文摘要:

Two analytical models for the ordinary mode propagating through inhomogeneous edge plasma layer are developed. Simple analytical expressions for diffusion-like angular and spatial beam width variation are obtained and compared to time-averaged results coming from 2D Maxwell's equations solver for different turbulence k-spectra and plasma conditions. The strong spatial broadening of microwave beam is predicted by the two approaches at realistic turbulent edge parameters for ECRH experiments at ITER.
