“神光Ⅱ”基频直接驱动内爆出中子靶制备工艺

Fabrication of the Neutron-producing Targets for the Fundamental Frequency Laser Direct Drive Implosion Experiments on the Shen-Guang Ⅱ

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 。

Techniques of fabricating the neutron producing targets for the direct drive implosion experiments on the Shen Guang Ⅱ(SG Ⅱ) device are described. The implosion targets and ablation targets fabricated by above techniques have been used in the direct drive of physical experiments by fundamental frequency laser on the SG Ⅱ device. And the neutron yields are about 4×10 9 and 6×10 8, respectively, which are in good agreement with the theoretical calculated results.
