研究了环面alfv<s:1>本征模在短波回旋动力学下经离子诱导散射的非线性饱和。发现热离子的非线性演化与热离子值有关。这里是等离子体的热磁压比。推导并估计了饱和水平和相关的能量-粒子输运系数。
Nonlinear saturation of a toroidal Alfvén eigenmode via ion induced scattering is investigated in the short-wavelength gyrokinetic regime. It is found that the nonlinear evolution depends on the thermal ion value. Here, is the plasma thermal to magnetic pressure ratio. Both the saturation levels and associated energetic-particle transport coefficients are derived and estimated correspondingly.
