Application of wavelet transform in anti-Compton phoswich detector for gamma spectrum

Changqi Liu, Kai Tao, Jinqiu Peng, Liming Huang et autres

The response of an anti-Compton phoswich detector to gamma rays was investigated using Monte-Carlo method, and the pulses from different crystal cases, including gamma deposition only in the LaBr3(Ce) or CsI(Tl) crystal and coincidence in both crystals, were analyzed. A novel pulse …

Calculation of the fission products for neutron-induced fission of 235U

Changqi Liu, Kai Tao, Liming Huang, E Dejun et autres

The fission model, G4ParaFissionModel, was enhanced in this study, mainly focusing on refining the energy dependence of the peak-to-valley ratio in the mass distribution and the energy dependence of the average total kinetic energy (TKE). The enhanced model was employed to investigate …

Research on the design of a radiation biodevice based on a compact D-D neutron generator

Dapeng Xu, Zhiqi Guo, Xu Yang, Xiaohou Bai et autres

In this research, we used a self-developed compact D-D neutron generator and designed a neutron radiation biological device. The research results showed that lead was the material with the best neutron permeability; thus, hard lead was selected as the structural material for …
