Magnetohydrodynamic (MHD) instabilities, such as kink and sausage instabilities, appeared on the gas-puff z-pinch plasma during the pinching process prevent spatial stability of hot spots, which are high energy density plasma regions produced by those instabilities on the z-pinch plasma column locally. Spatial stabilization of hot spots in the axial direction is very important to have practical applications. In this study, radius and velocity of the inwardly tilted gas-puff z-pinch plasma during the compression and efficiency of energy conversion were analyzed theoretically by solving one dimensional snowplow model (1D-SPM) and circuit equations which considered inductive pulsed power generator. Those results were compared with experimental results measured with framing photograph of the pinching plasma. Efficiency of energy conversion of an input energy supplied from the inductive pulsed power generator into kinetic energy of the z-pinch plasma and final pinching velocity of the plasma exceeded that in comparison with fast bank method. These results received benefit from the fast and large pinching current transferred from the inductive pulsed power generator.
