Abstract: During the past few years there has been extraordinary progress in developing fast Z-pinches for intense, high-energy density X-ray sources. The source is produced by converting the imploding Z-pinch material’s kinetic energy into the radiation, as it stagnates on the axis of load. The Sandia Z machine in this configuration routinely produces 2 MJ of soft X-ray with peck powers of ~ 200TW utilizing tungsten wire array loads. The theoretical analysis of the gas-puff Z-Pinch load to produce dense plasma X-ray source on “YANG” accelerator (~1.2MV, 1.5MA, 12 0ns) is researched in this paper. The annular radius, gas density and another parameters of the Z-Pinch load on “YANG” accelerator are presented. These parameters are available for to design a Z-pinch load.
