Abstract

The initial stage of the one-dimensional expansion of a hot electron cloud into a “warm” plasma (i.e., into a plasma with a finite electron temperature) is studied with allowance for plasma turbulence. It is shown that, in a nonturbulent plasma or in a plasma with sufficiently weak turbulence, counterstreaming warm plasma flows interpenetrate one another; in this process, the plasma flows are accelerated and form beams escaping from the heating region. A stronger turbulence gives rise to electron heat waves that also propagate away from the heating region.
