Abstract

This paper presents soft X-rays sources of X-pinch type based on the supersonic gas jets. Different variants of the nozzle design are considered. The high-order TVD finite-difference method on unstructured triangular meshes is used in order to solve gas dynamics equations and find the density distribution in the discharge gap. The results of mathematical modelling of the gas jet formation and of the dynamics of plasma originated from the gas jet for the chosen nozzle design and the results of the experimental study for the pinch current 250-300 kA are presented. The numerical simulations of the electrical explosions of the gas density configurations is performed with the help of radiative magnetohydrodynamics codes RAZRYAD (simplified geometry) and MARPLE (more realistic geometry).
