Development of axial-symmetric instability in a plasma cylinder with longitudinal current

The problem of the development of the axial-symmetrical instability in plasma cylinder with the longitudinal current is investigated by the method of numerical solution of the system of the equations of undissipated two-fluid electromagnetic gasodynamics. It is shown that the main phenomena, taking place on the final stage of a discharge in the systems of z-pinch type, are the consequence of process of the development of the considered instability. The formations of the condensed bunches of the dense hot plasma, generation of the electrical field and the acceleration of the charged particles along the axis of a discharge are concerned to this phenomena. 17 refs.; 9 figs
