Fully integrated simulations of fusion targets with a re-entrant cone are presented. Fuel assembly is modelled with one- and two-dimensional (2D) radiation hydrodynamic code. Fast electron acceleration in the cone is simulated with 2D planar particle-in-cell (PIC) codes. The fast electron transport and the fuel ignition are described self-consistently with the 2D cylindrical electron hybrid module coupled to the radiation hydrodynamic code. It is found that at laser intensities ~ 1020 W cm¿2, the front rippling at the cone tip generates strong magneto-static fields. It creates a strong divergence of the fast electron beam and significantly decreases its coupling to the fuel. A less divergent electron beam is needed for ignition of the fuel at the acceptable values of the ultra high intensity (UHI) laser beam energy. | |
