摘要：

In the present study, the explosion-proof detection integrated system (EPDS) is designed for social security. With the D-T neutron generator and BGO detector as the core components, the hardware modules in EPDS are optimized based on SNR evaluation in MCNP simulation. With the 50 MPa load on the internal surface in ANSYS software, the small deformation of wall (6.0354 mm) shows the good explosion-proof performance of EPDS. Furthermore, 6 kinds of explosives with 5 ordinary goods are measured, and the results shows the good resolution capability based on the element ratio method. Finally, with the investigation of detection results under different time gradient, the minimum detection time is discussed as 600 s.
