Paper Abstract

A series of 1D numerical simulations of X-ray emission of a Laser Megajoule baseline target has been performed using the radiation-hydrodynamics code FCI1. The results are presented in term of X-ray spectra, energies flowing through the Laser Entrance Holes (LEH) and through the hohlraum walls and in term of temporal analysis of burnthrough for a laser energy of 1.8 MJ and a total yield of 20 MJ. Parametric studies with wall thickness (20 to 100 micrometers ) and with 2 models of closing LEH are presented. Most of results are compared with LLNL numerical simulations.
