Beam-nonuniformity smoothing using density valley formed by ion beam deposition in an ICF fuel pellet

We study the beam non-uniformity smoothing effect of the radiation transport in the density valley formed by an ion-beam deposition in a heavy ion-beam inertial confinement fusion pellet by numerical simulations. The simulation results show that the radiation energy is confined in the density valley, and the beam non-uniformity can be smoothed out by the radiation transport along the density valley. In addition, an estimation for the Rayleigh-Taylor instability growth during the implosion phase is also presented.
