摘　　要：介绍了在阳加速器上进行的系列W丝阵Z箍缩物理实验,实验中阳加速器Marx充电电压60kV,负载电流输出0.85～1.00MA,电流上升时间75～90ns(10%～90%);进行软X光辐射功率测量的主要仪器是软X光闪烁体功率计,其核心部件为对50～1800eV X光具有平响应特性的蓝光闪烁体。给出了系列W丝阵Z箍缩实验软X光辐射功率测量结果,从软X光辐射输出随丝阵负载参数(包括丝阵直径、长度、丝数)变化关系讨论了钨丝阵内爆辐射特性,给出了阳加速器上各负载参数优化的结果:丝阵直径8mm,丝阵长度15mm,丝数24。同时对软X光辐射的空间分布特性进行了初步的探讨,给出了辐射功率在负载的轴向和径向的分布。A series of experiments were carried out to research the X-ray radiation characteristics of tungsten wire arrays on Yang accelerator.In those experiments,we charged the Marx generator of 60 kV,and the load current of 0.85-1.00 MA,the rise time of 75-90 ns（10%-90%）.A soft X-ray scintillator powermeter which responsed flatly to 50-1800 eV X-rays was used to measure the power of soft X-ray emitted from implosion plasma.In this paper,we present the measuring results of time-resolved soft X-ray radiation power,and discuss the radiation characteristics of implosion plasma by analyzing the correlations of soft X-ray radiant power and the diameter,length,wire number of the tungsten wire arrays.The optimizing wire array configuration parameters on Yang are as follows： 8 mm array diameter,15 mm wire length,and 24 wire number.We also present the radiant power difference in radial and axial directions of the wire arrays.
