描述了“神光Ⅱ”基频直接驱动内爆出中子靶制备工艺。用该工艺制备的爆推靶、烧蚀靶在“神光Ⅱ”装置上用基频光进行物理实验 ,分别获得了 4× 10 9个中子和 6× 10 8个中子的高中子产额 ,与理论计算的中子产额值符合较好 Describes the “Shenuang Ⅱ” fundamental frequency direct drive implosion neutron target preparation process. Using this technique, the target of blasting was fabricated and the ablation target was subjected to physical experiments with “fundamental light” on a “ShenGuang Ⅱ” device to obtain 4 × 10 9 neutrons and 6 × 10 8 neutrons respectively The value of neutron yield is in good agreement with the theoretical calculation
