Gas-puff z-pinch plasmas driven by inductive energy storage pulsed power generator

An inductive energy storage pulsed power generator is used as a power source of gas-puff 2-pinch plasmas to investigate the effect of the steepened current rise on the intensity of soft X-rays and the spatial reproducibility of the hot spots. Furthermore, two kinds of electrodes, which are solid and mesh type, are used to investigate the influence of the incident gas distribution on the z-pinch plasmas. Tn the case of the solid electrode, the axial symmetry of the plasma column during pinching and the spatial reproducibility of the hot spots is improved not only by the steepened current rise but also the induced pulsed voltage. On the other hand, the improvement in the plasma column and the reproducibility due to the inductive pulsed power generator is unclear in the case of mesh electrode. In this experiment, the uniform gas distribution has priority over the current rise time and the induced pulsed voltage.
