Multiple Time and Spatial Scale Plasma Simulation -Prospect Based on Current Status- 4.Prospect for Multiple Time and Spatial Scale Simulation Research of Laser Fusion Plasmas

Abstract

Reviewed is the development of the integrated simulation code related to laser fusion plasma research. In particular, the simulation system for describing ultra-intense laser interaction with high density plasmas is discussed. In ultra-intense laser plasma interaction, the relativistic electron current reaches a few hundred mega amperes and generates strong magnetic fields which control the electron transport. Therefore, the simulation system should include particle-in-cell simulation for laser plasma interactions, Fokker-Planck simulation and hybrid simulation for transport and dense plasma heating, and radiation hydrodynamic simulation for laser implosion and fusion burning. This paper reports the present status of the research regarding those simulations and how the above 4 simulation codes are interconnected as parts of the study of multi-space-time scale laser fusion plasma phenomena.
