An investigation was made of the excitation of space-charge waves in a double-beam plasma system, of the mechanism of plasma expansion by the ponderomotive force of high-frequency oscillations, and of the process of excitation of ion-acoustic oscillations as a result of mixing of space-charge waves. Strong expulsion of the plasma in the region of the maximum density of hf oscillations (deltan/napprox.0.9) was observed in the case of resonant mode merging. The process excited intense ion-acoustic waves whose amplitudes were sufficient for the capture and acceleration of plasma ions.
