PLASMA KINETIC EFFECTS IN STOCHASTIC HELICAL FIELD

The kinetic equation for a plasma in a stochastic electromagnetic heli cal field is constructed and studied. The kinetic equation contains an additional term, proportional to the helicity. The evolution of the m ain moments of the distribution function is considered. A solution des cribing the evolution of the distribution function for arbitrary initi al conditions is found and possible consequences of presence of the he licity term are discussed. A model example is considered when a single -momentum electron beam with an inhomogeneous velocity profile creates a new particle flow in the transverse direction, so that the resultin g flow also possesses the helicity.
