摘要：

It is demonstrated both numerically and analytically that the energetic particle driven Alfven wave instability saturates when the Alfven wave fluctuations are still quasi-coherent. The saturation is due to particle velocity space diffusion which steepens the velocity gradient of the resonant particles, thereby enhancing wave damping (Landau damping).
