摘要: 零维模型负载优化设计制作的单层和双层铝丝阵负载，在俄罗斯S-300强流发生器上，利用“狭缝+闪烁体+光电探测器”X光功率测量系统对X光辐射特性参数进行了诊断。实验获得单层丝阵负载的辐射功率为(0.31±0.19) TW，辐射总能量为(16.93±7.45) kJ，脉宽为(18.41±5.00) ns；双层丝阵负载的辐射功率为(0.37±0.12) TW，辐射总能量为(16.40±3.99) kJ，脉宽为(13.45±3.50) ns。实验结果表明，双层丝阵负载辐射功率高于单层19.4%，信号脉宽窄4.96 ns。Abstract: An X-ray power measuring system composed of slit, scintillator and phototube is used to diagnose the characteristic parameters of soft X-ray generated in the implosion of Al wire array Z-pinch experiments on the S-300 facility at Kurchatov Institute. Wire array loads based on zero-dimension thin shell model are designed for experiments. For single wire array load, the experiment gets an X-ray power of (0.31±0.19) TW, total radiated energy of (16.40±7.45) kJ, and pulse width of (18.41±5.00) ns. For nested wire array load, an X-ray power of (0.37±0.12 ) TW, total radiated energy of (16.93±3.99) kJ, and pulse width of (13.45±3.50) ns are achieved. The experimental results of different wire array loads show that the total energy achieved by nested wire array is 19.4% higher than that of
