Transverse dynamics of a collisionless plasma column in a homogeneous magnetic field

Results of a general study of a set of kinetic equations describing the dyn amics of a two-component quasineutral collisionless plasma column in a homo geneous, nonstationary magnetic field are presented. The dynamics of the co lumn is found to be completely determined by initial values of total kineti c energy of a plasma total angular momentum of each plasma component, and t otal mass of a plasma. In the case of a stationary magnetic held the column cross section is shown to oscillate harmonically at the low-hybrid frequen cy. The peculiarities of the plasma dynamics found are confirmed by self-si milar solutions of a set of two Vlasov kinetic equations.
