Outline of Final Research Achievements

This research is aimed at the increase of the heating efficiency for the fast ignition scheme of inertial confinement fusion. The fast ignition scheme has large potential to reduce the ignition energy required for thermonuclear burn. However, the heating efficiency of ultra-intense laser to the compressed core is not enough yet to initiate the thermonuclear burn efficiently. In order to increase the heating efficiency, we developed the two-dimensional radiation hydrodynamic simulation code to calculate the implosion with laser non-uniformity. Also, we calculate the electrical conductivity to simulate the diffusion of external magnetic field into the cone target and generation of pre-plasmas due the Joule-heating of eddy current driven by the temporal change of the magnetic fields. Now, we can simulate the improvement of heating efficiency of fast ignition based on these progresses of numerical modeling.
