【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。更多还原

【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 single wire array,and the pulse width for nested wire array decreases by 4.96 ns compared to that for single wire array.更多还原
