摘要
在与平衡磁面相联系的坐标系下 ,用剪切阿尔芬波近似给出了统一描述托卡马克等离子体理想磁流体线性运动的本征模方程。利用此方程 ,可以进一步给出大尺度扰动 (扭曲摸、低模数气球模、阿尔芬模 )和小尺度扰动 (高模数气球模、Mercier模 )的本征模方程。
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.
