Ignition and Burning Calculations in Inertial Confinement Fusion Driven by Light Ion Beam

We study burning processes in inertial confinement fusion driven by intense light ion beam (LIB) with a 1-D Lagrangian code. It is found that burning processes have two phases; they are an ignition and its propagation phase, and a recompression phase. In the ignition of nuclear reactions and its propagation phase, ρ R is kept at 1.5 g/cm 2 but in the recompression phase ρ R increases steeply up to 3.5 g/cm 2 . An Au shell surrounding a DT fuel plays two roles in each phase i.e. in the former phase it acts as a tamper to confine the DT fuel and in the latter phase it recompresses the DT fuel to lead high ρ R .
