摘要

O'Neil and ATtshul et al. discussed the nonlinear theory of large-amplitude electron plasma waves (EPW). Franklin reported the experimental results of periodic amplitude variation of EPW caused by wave-particle interaction. In 1990, we discussed the nonlinear Landau damping caused by electrons trapped in ion acoustic wave (IAW) with IAW drift instability. In the present note we will study theoretically and experimentally the three stages for the IAW amplitudes to develop from linear Landau damping (growing) to nonlinear effects. The experiments were performed in a double plasma device, which has been described previously.
