Outline of Final Research Achievements

Conventional theories of solid-state physics and plasma science are not suitable to explain a state during the phase transition process. Although the state is common phenomena between a solid and plasma, the physical properties are unclear. In an inertial confinement fusion scenario, the fusion output is given by nuclear fusion reactions in dense and high temperature plasma produced by an implosion process of a fuel pellet. Therefore understanding of the properties and the process is important for nuclear fusion studies. In this study, the experimental setup for generation and measurement of dense state during the similar time scale of implosion process was constructed with an extreme intense pulsed power generator. The measurement method of the physical properties, such as electrical conductivity, thermal conductivity, specific heat, equation-of-state, and so on, in the unique state of dense material was considered and established by using the constructed setup.
