摘　　要：在'神光Ⅱ'激光装置首轮辐射驱动内爆实验中用一套超快猝灭闪烁探测器系统测量了聚变燃料离子温度.分别通过宇宙射线和内爆δ脉冲中子源标定了探测系统的时间响应函数.实验表明:'神光Ⅱ' 辐射驱动聚变燃料离子温度约为2～3 keV.An ultra-fast quenched plastic scintillation detector was used to measure fusion fuel ion temperature for indirectly driven implosion in the experiment conducteded at Shengguang Ⅱ laser facility. The time response functions of the detection system were calibrated by implosion neutrons from a DT-filled capsule and cosmic ray, respectively. The experimental result shows that fusion fuel ion temperatures for indirectly driven implosion at Shengguang Ⅱ are almost between 2-3 keV.
