摘　　要：在强光一号装置上进行了钨丝阵和铝丝阵分别加氘丝(C_8D_8)Z箍缩实验。利用X光功率谱仪和十分幅纳秒X光分幅相机获得了X光功率和不同时刻负载内爆的X光图像。比较两种负载类型的功率谱仪数据,钨丝阵加氘丝负载的X光功率及X光辐射总能量都比较高。从图像来看,钨丝阵加镀银聚氘丝负载在箍缩过程中较铝丝阵加氘丝负载均匀。中子飞行时间谱仪的结果表明钨丝阵加氘丝Z箍缩等离子体能够产生最高1.5×10~9的脉冲DD中子,铝丝阵加氘丝负载最高产生DD中子3.4×10~8。Z-pinch experiments with tungsten wire array and aluminium wire array centered,respectively,by a deuterated fiber(C_8D_8) have been carried out on Qiangguang-1 facility.X-ray radiation power was obtained by an X-ray power meter(XRPM) and soft X-ray images were given by a ten-frame time-resolved pinhole camera.Comparing XRPM's data of both two kinds of loads,tungsten wire arrays with C_8D_8 have a higher record of X-ray power and total radiation energy.The framing images indicate that implosions of tungsten ...
