Outline of Final Research Achievements

We have developed a two-dimensional resistive electromagnetic radiation hydrodynamic simulation code for laser plasma to investigate the influence of magnetic field on hydrodynamics and application of strong magnetic field. We have verified that generation of strong magnetic and its compression using laser driven implosion. Furthermore, we found that due to the anisotropy of electron heat conduction in strong magnetic field, hydrodynamic instability was induced, and it was not compressed properly in shell implosion. We proposed the spherical solid target instead of shell target.
Some numerical examples were shown to demonstrate the application of laser-produced strong magnetic field. For example, control of the high energy electron beam is demonstrated using hybrid simulation, which is important for fast ignition of laser fusion.
