Nonlinear Damping of Electron Plasma Oscillations

抄録

The behavior of the sideband wave is studied analytically in a one-dimensional plasma in which a large-amplitude, monochromatic electron plasma wave is applied. The distortion of the electron distribution function is calculated by the Liouville operator formalism. It is shown that the damping rate of the sideband wave, which is proportional to the amplitude of the applied field under usual experimental conditions, changes to be proportional to its square root in the restricted region.
