Abstract

The interaction of the BGK-wave with sinusoidal density perturbation in the one-dimensional plasma with fixed ions was studied in numerical experiments (PIC-method). It was shown that this interaction leads to the conversion into the direct and backward Langmuir waves with the wave numbers N=N{sub e}{+-}{beta}N{sub i}, {beta}=1,2,3... In the cases with n-tilde/n{sub 0} {approx}0,6 - 0,9 the wide spectrum of the conversion modes is excited up to {beta} {approx} 8 during one plasma period. In these cases the main role plays the large scale stochasticity of the electron motion which shows itself in the region of the crossing trapping regions of the shortwavelength conversiopn modes. The energy of the BGK-wave is transfered through the longwavelength conversion modes into the shortwavelength modes, where it is absorbed by the plasma electrons. As a result the electric field energy is damped and the BGK-wave is destroyed. 8 refs., 18 figs., 1 tab.
