Abstract

The effect of acoustic waves on plasma parameters is considered. It is shown that longitudinal ultrasonic waves applied to a homogeneous plasma column and directed along the electric field cause lamination. Relationships are obtained between the electron densities in the compressed and rarefied plasma layers and the sound intensity. It is established that as the sound intensity is increased the electron density decreases in the compressed layers; in the rarefied layers it increases. For a constant sound intensity in the plasma, an increase in gas pressure leads to a reduction in the nernec ratio of the electron densities in the rarefied and compressed layers, i.e. a reduction in gas pressure leads to a rise in the spatial modulation of the plasma.
