Thermalization of the directed motion of plasmoids by a turbulent skin-layer discharge

Slowing down of oppositely moving plasma streams is observed experimentally when a direct skin-layer current of density j>en (T/sub e//M)/sup 1///sup 2/ is passed through them. The energy of the translational motion is transformed in this case into thermal energy. The plasma column is heated along the radius from the skin layer toward the axis at the velocity of ion sound; the heating is accompanied by intense noise with a frequency on the order of ..omega../sub p i/. A theoretical explanation of the phenomenon is proposed, based on the nonlinear instability of a two-stream plasma to finite-amplitude perturbations originating in the skin layer.
