托卡马克中离散阿尔芬不稳定性的动理学分析

Kinetic Analysis of Discrete-Alfven Instability in Tokamak

动理学是描述等离子体的重要方法。本文介绍了动理学的一种近似处理——回旋动理学,并在简单模型下演示了线性回旋动理学方程近似过程。结合ITER(International Thermonuclear Experimental Reactor)设计参数和模拟放电实验数据,利用线性回旋近似研究环形聚变等离子体中高能量粒子的动理学效应对离散阿尔芬本征模(αTAE)的影响。

Kinetic description is an important method in plasmas studies. The Gyrokinetic theory which is an approximate treatment of kinetic was introduced and linear Gyro-kinetic approximation was demonstrated in the simple model. Based on the ITER（ International Thermonuclear Experimental Reactor） design parameters and associated simulated data,the kinetic effect of the energetic particles in toroidal fusion plasmas on the discrete-Alfven eigenmodes was studied with linear Gyro-kinetic approximation.
