Modeling of fast capillary-discharge for soft x-ray lasers

Abstract

In this work we present the results of the numerical investigations of the one-dimensional single-fluid magneto-hydrodynamics (MHD) model, with separate electron and ion temperatures, of a capillary-discharge collisional soft x-ray laser. The MHD equations are solved by the Lagrangian cylindrical geometry approach. The effects of the gas filling pressure on the plasma densities and temperatures, and implosion-pinch phase for soft x-ray lasing conditions have been analyzed. The results are compared with experimental measurements of the operating pressure ranges.
