摘要: 采用打靶法,数值求解了在负磁剪切托卡马克等离子体中离子温度梯度驱动的复本征模方程.数值计算表明,环向旋转剪切流可以整体上改变剪切板ηi不稳定性.在等离子体极小q磁面附近的芯部区域,环向剪切流有稳定ηi模的作用.

关键词: 负磁剪切, 本征模方程, 打靶法

Abstract: An eigenmode equation of ion temperature gradient driven instability in a tokamak plasma with negative magnetic shear is solved numerically by the shooting method.Numerical calculations show that the toroidal rotation sheared flow can modify the sheared slab ηi instability and has a stabilizing ηi role in the plasma core near minimum q magnetic surface.

Key words: negative magnetic shear, eigenmode equation, shooting method
