2D dynamics of double liner imploded by high current pulse

Modeling of implosion of nested tungsten wire arrays on the Z generator by two-dimensional magnetohydrodynamic code ZETA including radiation transport with non-LTE-LTE approximation is performed in order to reproduce experimental results. It is shown that it is possible to fit the experimental results if 10% level of initial mass perturbation of the tungsten wire arrays is imposed. The implosion dynamics and the Rayleigh-Taylor instability developed, are discussed. Plasma of the z-pinch is in nonLTE regime.
