考虑到弯曲系统中微观不稳定性的谱问题,针对圆柱等离子体的简单情况,提出了求解全局回旋方程的方法。事实证明,它们对于计算离子温度梯度 (ITG) 类型模式的完整不稳定谱是有效的,并且适用于托卡马克配置的二维积分方程。
Considering the spectral problem of microinstabilities in a curved system, methods for solving the global gyrokinetic equation are presented for the simple case of a cylindrical plasma. They prove to be efficient for computing the full unstable spectrum of ion temperature gradient (ITG) type modes and have shown to be applicable to the two-dimensional integral equation of tokamak configurations.
