| Research Abstract |
Behaviors of warm dense plasmas and structures of strong shock waves were studied using pulse power device and intense particle beams. Electrical conductivities of warm-dense metallic plasma were measured as a function of density and temperature using pulse power driven electrical discharges. The results showed that, regardless of materials, the conductivity has a minimum value at a state with few tenth of solid density and several thousand K which disappears with the temperature rise. The structure of strong plasma shock waves in which radiation transport plays an important role, was discussed using electro-magnetically driven high speed flows. For generation of high power particle beams, the evolution and energy dissipation processes of intense beams during bunch compression processes were discussed using a beam modulation simulator.
