Cone Material Dependence of Fast Ignition Core Heating

ORAL

Abstract

In cone-guiding fast ignition, the cone material affects the heating performance through the fast electron generation and transport processes [1]. In the present paper, we advanced the research on the cone material dependence of core heating properties with a help of the integrated simulations. By assuming Au, Cu and DLC as the cone material, first we evaluate the pre-plasma generation by radiation-hydro simulations. Using those pre-plasma profiles, the fast electron generation is evaluated by PIC simulations including collision and ionization processes. Then, the fast electron transport is calculated by Fokker-Planck code. In addition to the fundamental feature of cone material dependence, we will discuss the fast electron guiding by self-generated and externally-applied magnetic field, and also radiation effects.\\[4pt] [1] T.
