摘　　要：利用激光驱动充 DT燃料的内爆靶丸 ,完成了“神光 ”激光装置首轮内爆出中子实验。通过超快猝灭塑料闪烁探测器测到了直接驱动内爆中子产额。中子产额 10 7～ 10 9,测量误差± 7%～± 10 %。中子产额实验值与理论部提供的计算值 (爆推靶 )在± 2 0 %范围内一致。An ultra fast quenched plastic scintillation detector was used to measure DT neutron yield in the first experiment performed on the ShengguangⅡ laser facility. The uncertainties of neutron yields were (±7%～10%. The measured implosion neutron yields were in agreement with the calculated ones supplied by Institute of Applied Physics and Computational Mathematics in the range of ±20%.
