Importance of radiation effects in ion-beam-driven inertial fusion target calculations: Compensation of range shortening by radiation transport in ion-beam-generated plasmas
In this paper computer simulation results showing that radiation can compensate for range shortening in ion-beam inertial fusion targets are presented. Simulation results of ablation, compression, ignition, burn, and hydrodynamic stability of a heavy ion-beam-driven, reactor-size, inertial confinement fusion (ICF) target including radiation transport are also reported. In this target design the fuel is protected against radiative preheat by a high-Z, high-rho lead radiation shield, and the fuel is separated from the radiation shield by a low-Z, low-rho lithium cushion. This avoids mixing of the lead from the radiation shield into the fuel at the end of the implosion. The target is driven by 10 GeV Bi/sup + +/ ions, and it yields an output energy of approx.690 MJ for an imput energy of approx.4.56 MJ, so that the overall target gain is approx.152. The peak power in the input pulse is 500 TW.
