采用磁力线为直线的坐标系 ,进一步将托卡马克理想磁流体剪切阿尔芬运动方程展开 ,获得了描述低模数环形阿尔芬本征模 (TAE和EAE)
A unified eigenmode equation of ideal MHD instabilities in tokamak is derived by using the shear Alfvén approximation in the coordinates associated with the magnetic surfaces.Based on this equation,eigenmode equations governing the large scale perturbation (such as the kink mode,the low n ballooning mode and the Alfvén mode) and small scale perturbation (such as the high n ballooning mode,the local mode) can be further deduced.In this present study,the part of the small scale perturbation is discussed in detail.
