FAST DYNAMICS OF THE CURRENT IN A LINER ACCELERATED BY THE MAGNETIC-FIELD OF THE CURRENT

A study is made of the fast two-dimensional dynamics of magnetic field s during the implosion of a light strongly radiating Liner compressed by its own magnetic field. A general solution to the initial electron magnetohydrodynamic equations is derived based on the assumption that, during the implosion, all the parts of the liner move with the same a cceleration. On the basis of this solution, several particular nonline ar solutions describing the temporal evolution of the scale length of the modulation of experimentally observed radiation from the outer lay ers of the Liner are obtained and analyzed. For one of these solutions , the results of analytical and numerical studies are compared. Criter ia are obtained for the stability of the implosion of an emitting line r against the fast processes under consideration.
