建立了一套门控闪烁测量系统(门控ST-PMT系统),测量了稠密等离子体聚焦(DPF)波形后沿中子峰下3~4个量级的物理图像,分别讨论了长电缆对DPF D-D,D-T中子峰下3~4个量级波形测量的影响,采用数学方法分析了长电缆作为频率滤波函数在解逆卷积函数中的应用,解析了电缆带宽对测量结果的影响。
The influence of the Fourier Transform on long cable in the measurement of fall time of DPF neutron profile is discussed by mathematical methods.The application of anti-convolution function with the Fourier Transform on long cable is analysed.The time interval between the peak time and the time that the height falls 3 orders of magnitude after peak is measured with gated-detector array system which consists of PMT(photomultiplier tube) and organic scintillation crystal.
