Embodiment 1
[0036] Embodiment 1: the present invention comprises 235U nuclear components, a detector with a prompt neutron decay constant of 0.0375 is used as an example to illustrate that all neutron pulse signals are collected through 3 channels. The first channel is the source channel, which is used to directly collect the neutron pulse signal from the 252Cf neutron source. The second channel and the third channel are used to collect the neutron pulse signal generated by the detector body excited by the neutron source. The prompt neutron attenuation constant is calculated by using the cross-correlation function CC12 and the cross-power spectral density function G12 between the first channel and the second channel respectively. Obviously, the cross-correlation function CC13 between the first channel and the third channel and The cross power spectral density function G13 can also obtain similar results.
[0037] The first step is to collect the neutron pulse, the sampling frequency is ...
Embodiment 2
[0046] Embodiment 2: During the measurement process, the collected neutron pulse signal is divided into 2×10 5 blocks, a total of 20 cycles were performed. Therefore, a total of 20 sets of data were measured by the two methods, such as Figure 7 shown. Its mean and variance are shown in Table 1. due to satisfaction and It is easy to get the prompt neutron decay constant obtained in this measurement as
