在神光Ⅲ主机装置上，利用已经建成的两个激光束组，开展了激光间接驱动内爆物理磨合实验，是神光Ⅲ主机装置首次出中子实验。实验采用1400 μm×2100 μm黑腔，500 μm的塑料靶丸充1 MPa的DD燃料，激光从黑腔两端55°注入。实验获得的最高中子产额为9.7×108。实验结果表明，实验黑腔的耦合效率约为50%；使用的黑腔偏长，靶丸被压缩为“薄饼形”；中子产额和激光能量正相关；中子发射峰值时刻主要依赖于烧蚀层厚度。

The implosion experiment with double quads on SGⅢ facility was the first time laser indirect-drive implosion experiment, also the first time neutron experiment. The experiments used 1400 μm×2100 μm hohlraum with 1000 μm LEH and 500 μm CH target with 1 MPa DD fuel, and the laser was injected the hohlraum by 55 °. The highest neutron yield was 9.7×108, up to now, the highest indirect-drive DD neutron yield in domestic experiment. The experimental results show that the coupling efficiency of the hohlraum approximates 50%; the hohlraum is too long, and the pellet is compressed to a “pancake”; neutron yield is positively correlated with the laser energy; the Bang Time depends on the thickness of the ablative layer.
