通过数值模拟研究了重离子束惯性约束聚变芯块中离子束沉积形成的密度谷中辐射输运的束流非均匀性平滑效应。模拟结果表明，辐射能量被限制在密度谷内，辐射沿密度谷沿着输运可以平滑束流的不均匀性。此外，还对内爆阶段的瑞利-泰勒不稳定性进行了估计。
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 inertial confinement fusion pellet by numerical simulations. The simulation results show that the radiation energy is confined in the density valley, and the beam nonuniformity can be smoothed out by the radiation transport along the density valley. In addition, an estimation for the Rayleigh-Taylor instability during the implosion phase is also presented.
