Drift Instability

The linear growth rate of the crossfield current-driven ion-acoustic instability is obtained for any equilibrium particle velocity distribution function of the type . Quasi-linear theory is then used to investigate the saturation of the instability. Several associated features, namely, particle diffusion in velocity space, anomalous resistivity, energy distribution and electron and ion heating rates are evaluated for a Maxwellian distribution. Finally, a brief comparison is made with the heating rates associated with the electron cyclotron drift instability.

Z Pinch

An effect of the random plasma inhomogeneity onto the scenario of ion-acoustic anomalous resistivity is considered. It is shown that such an inhomogeneity could be more efficient than nonlinear effects to determine the turbulent resistivity. In application to Z-pinches, some peculiarities of the skin-effect are considered, in particular, subsequent inhomogeneity of the current penetration into the conducting medium.
