Abstract

The dynamics of capillary plasmas in regimes where soft x-ray amplification has been observed is investigated by means of a magnetohydrodynamic one-dimensional code that takes into account dissipative processes, ablation, and ionization of the wall material. The formation of a hot dense plasma kernel close to the channel axis due to converging shock waves is observed. Its localization and time evolution are in close agreement with experimental observations of Ne-like Ar emission. It is pointed out that the redistribution of the electric current between argon and ablated wall plasmas strongly influences the kernel plasma parameters, Dimensionless parameters describing plasma dynamics are found, and empirical scaling laws for the density and temperature of the kernel plasma as a function of the discharge parameters are presented.
