In this paper the development of capillary discharge soft X ray laser is introduced. Using XDCH, a one dimensional Lagrangian magneto hydrodynamics code, the simulation results of a discharge pumped 2p 53p→2p 53s transition 46.9 nm laser in Ne like Ar are presented. The physical schemes in Ne like Ar 46.9 nm laser are also studied. Finally the possibility of generating soft X-ray laser from the home made setup is discussed.
