“…Hashemzadeh [41][42][43] has carried out particle-in-cell simulation of Buneman instability for q non-extensive distribution and effect of negative ions on the Buneman instability. There is ample amount of other simulation works dealing with Buneman instability in various applications in space and laboratory plasmas that are too numerous to cite.…”

Spatio-temporal evolution of Buneman instability has been followed numerically till its quasilinear quenching and beyond, using an in-house developed electrostatic 1Dand for a wide range of electron to ion mass ratios (m/M), growth rate obtained from simulation agrees well with the numerical solution of the fourth order dispersion relation. Quasi-linear saturation of Buneman instability occurs when ratio of electrostatic field energy density () reaches up to a constant value, which as predicted by Hirose [Plasma Physics 20, 481(1978)], is independent of initial electron drift velocity but depends on electron to ion mass ratio m/M as. This result stands verified in our simulations. Growth of the instability beyond the first saturation (quasilinear saturation ) till its final saturation [Ishihara et. al., PRL 44, 1404(1980] follows an algebraic scaling with time. In contrast to the quasilinear saturation, the ratio of final saturated electrostatic field energy density to initial kinetic energy density, is relatively independent of electron to ion mass ratio and is found to depend only on the initial drift velocity. Beyond the final saturation, electron phase space holes coupled to large amplitude ion solitary waves, a state known as coupled hole-soliton , are seen in our simulations. The propagation characteristics ( amplitude -speed relation ) of these coherent modes is found to be consistent with

The stability of a fully ionized plasma with a relative electron-ion (e-i) motion is considered taking into account the e-i collisions of high level. The relative e-i drift speed is assumed to be much higher than the thermal spread of electrons, and in the absence of collisions the system is subject to the low frequency and strongly growing Buneman instability. The transport equation with the Landau collision integral is solved taking into account the dependence of the collision frequency on the velocity of colliding particles. The effective frequency of e-i collisions is determined as a function of the system parameters. It is shown that with an increase in the level of e-i collisions the Buneman instability gradually transforms to the instability of dissipative type. This transition is traced in detail. The dependence of the growth rate on collision frequency upon this transformation is obtained.
