Description

In this paper, the effects of nonvanishing plasma parameter 1/nλDe3 on the nonlinear beam-plasma interaction process are discussed on the basis of numerical solutions of weak turbulence equation. The finiteness of the plasma parameter is directly related to the single-particle spontaneous fluctuation phenomena. It is shown that spontaneous fluctuations promote the Langmuir condensation effect, lead to a finite level of ambient turbulence, and enhance nonlinear mode coupling process
