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.

利用脉冲功率装置和强流粒子束研究了暖稠密等离子体的行为和强激波的结构。利用脉冲功率驱动放电测量了温密金属等离子体的电导率随密度和温度的变化。结果表明，无论何种材料，在密度为固体的十分之几、温度为几千K时，电导率都有一个极小值，随着温度的升高，该极小值消失。利用电磁驱动的高速流动，讨论了强等离子体冲击波的结构，其中辐射输运起着重要作用。针对高功率粒子束的产生，利用束流调制模拟器研究了强流束在束团压缩过程中的演化和能量耗散过程。
