Beam non-uniformity smoothing using density valley formed by heavy ion beam deposition in inertial confinement fusion fuel pellet

We study the beam nonuniformity smoothing effect of radiation transport in the density valley formed by an ion-beam deposition in a heavy ion-beam ine rtial confinement fusion pellet by numerical simulations. The simulation re sults show that the radiation energy is confined in the density valley, and the beam nonuniformity can be smoothed out by the radiation transport alon g the density valley. In addition, an estimation for the Rayleigh-Taylor in stability during the implosion phase is also presented.
