Abstract

The development of Buneman's kinetic-type instability in plasma with hot ions and cold electrons is investigated. Expressions for the frequencies and growth rates of oscillations when the current velocity slightly exceeds the instability threshold velocity have been derived in the linear approximation. The quasilinear theory of instabilities has been developed, and it has been shown that the quasi-linear effects lead to the amplification of the instability.
