Inertial confinement fusion implosions using capsules with two concentric shells separated by a low density region (double shells) are reported which closely follow one dimensional (1D) radiatively driven hydrodynamics simulations. Capsule designs which mitigate Au M-band radiation asymmetries appear to correspond more closely to 1D simulations than targets lacking mitigation of hohlraum drive M-band nonuniformities. One capsule design achieves over 50% of the unperturbed 1D calculated yield at a convergence ratio of 25.5, comparable to that of a double-shell design for an ignition capsule at the National Ignition Facility.
据报道,使用由低密度区域分隔的两个同心壳的胶囊(双壳)进行的惯性约束聚变内爆,与一维(1D)辐射驱动流体动力学模拟结果密切相符。与未减轻黑体腔驱动M波段不均匀性的靶相比,减轻金M波段辐射不对称性的胶囊设计似乎与1D模拟更接近。一种胶囊设计在收敛比为25.5时实现了超过未受扰动的1D计算产额的50%,这与国家点火设施点火胶囊的双壳设计相当。
