Analysis of compression and burn of ion-beam inertial fusion targets including radiation transport
This paper presents implosion results of a new ion-beam inertial fusion target which has been designed for use in a reactor study, HIBALL-II. This target has been simulated using an updated version of the MEDUSA-KA code which includes radiation transport. The target contains 4 mg of DT fuel which is protected against radiative preheat by a high-Z, high-ρ lead radiation shield. The radiation shield is separated from the fuel by a reasonable thickness of lithium to improve the hydrodynamic stability. The target is driven by 10GeV Bi++ ions and the peak power in the pulse is 500 TW. The total input energy is ∼ 4.38 MJ and the gain is ∼ 152.
