Polarity effect on the behavior of gas puff z-pinch plasma produced by IPP system

Summary form only given, as follows. Hot spots produced by gas-puff z-pinch plasma which are high energy density plasma regions radiate intensive soft X-rays. A gas-puff z-pinch is expected in industrial applications such as soft X-ray lithography, microscopy and lasers. In these cases, the scattering of hot spots is important when the gas-puff z-pinch plasma is used as a point source of soft X-rays. Previous results in our study showed the reduction of radial displacement of hot spots in positive voltage shots by using a IPP (inductive pulsed power) system. In the paper, the voltage polarities effect on the z-pinch plasma behavior, soft X-ray emission and spatial distribution of hot spots are described.
