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.

使用脉冲功率装置和强粒子束研究了热致密等离子体的行为和强冲击波的结构。使用脉冲功率驱动放电测量热致密金属等离子体的电导率作为密度和温度的函数。结果表明，无论何种材料，电导率在固体密度的十分之一到几千K的状态下都有最小值，并随着温度的升高而消失。使用电磁驱动的高速流讨论了强等离子体冲击波的结构，其中辐射传输起着重要作用。为了产生高功率粒子束，使用光束调制模拟器讨论了束压缩过程中强束流的演化和能量耗散过程。
