Abstract
The stability of drift wave in a plasma with dissipation due to ion viscosity is examined. If the wave amplitude exceeds a threshold value, determined by ion-ion collisions, large-scale perturbations (i.e., with scales much greater than the drift wave length) grow. This effect is analogous to the negative viscosity effect in hydrodynamics. Maximum growth rate belongs to perturbations which are periodical along plasma inhomogeneity and constant in transverse direction, i.e. azimuthal direction in cylindrical geometry (zonal dissipative structures). The analysis of nonlinear stage of large-scale instability shows that the soliton-like large-scale structures of the electric field and vorticity are possible (dissipative solitons). 13 refs.; 2 figs. (author).
