Abstract:
A multi-dimensional radiation hydrodynamic code is developed and is applied to the interaction of intense ion beam with plasmas. The hydrocode is based on a newly developed, highly-accurate scheme CIP (Cubic-Interpolated Pseudoparticle). The radiation transport is solved with the SSI (Symmetrical Semi-Implicit) scheme, which is quite easily implemented and is 4-5 times faster than the ICCG. The Thomas-Fermi EOS (equation of state) is used for the atomic data and the Tsakiris and Eidmann formula for the Rosse-land mean-free path. This newly developed two-dimensional code is used to design an extraction method of the radiation from the high temperature regin heated by ion beam. The ion beam of 3 TW/cm^2 is converted into the soft X-ray of 40 TW/cm^2 at the surface of the radiation emitter.
