Double Shell Liner Implosion Experiments

It is well known that plasma liner implosions are subject to MHD instabilities. The imploding liner break up when implosion approaches the axis and, as the result, the liner radial compression ratio is restricted. An initial axial magnetic field have a stabilizing effect on the liner implosion. But the axial magnetic field that is necessary to stabilize the liner implosion is too high to obtain the radial compression ratio r{sub o}/r{sub f} > 20. Some methods of the liner stabilization in addition to the entraining of an initial magnetic field were used in the experiments on the SNOP-3 generator. The stable plasma pinches were formed, as the inner shell imploded. These plasma parameters are suitable for x-ray lasing experiments.
