Integrated simulations of core heating in cone-guiding fast ignition, FIREX-I

Abstract

The core heating properties of a Au cone-attached CD shell target in FIREX-I were investigated by the integrated simulations with FI3 code systems. The importance of fat electron transport in the deformed cone tip was shown. In addition to the collisional scattering and drag in the Au cone, the strong resistive magnetic field is generated at the top of the cone tip when the tip shape is deformed. Due to this field, the fast electrons are strongly scattered, and then the core heating efficiency becomes smaller compared with the case neglecting the magnetic field. © 2010 IOP Publishing Ltd.
