| Outline of Final Research Achievements |
In order to improve the numerical analysis of the radiation hydrodynamic simulation when a solid target is irradiated with a relatively high-intensity laser (10^15 W/cm^2), we have developed a model of the kinetic effect considering the microscopic nonlinear laser-plasma interaction (LPI). LPI simulations have been carried out to create a database of stimulated raman scattering and stimulated brilliant scattering for long density scale length case. The time dependence of laser absorption, hot electron generation and scale length dependence were shown and modeled. We also extended the diffusion approximation model for the radiation hydrodynamic simulation code, where M1 model was developed in order to consider the high energy electron transport with strong anisotropy.

| Academic Significance and Societal Importance of the Research Achievements |
高エネルギー密度科学は様々な可能性を持っている。しかし、同分野の多くの実験は極限状態でであることから計測が難しく、科学的な解明の妨げになっている。一方、計算シミュレーションは比較的容易に数値実験を行うことができる。今回の成果は、流体シミュレーションに運動論的な効果をモデル化して組み込むことで極限状態のシミュレーションの精度を大きく向上させるものである。
