Abstract

Abstract: In the research, the Nuclide Identification and Quantitative Analysis System (NIQAS) for the identification of hazardous goods was designed and optimized by MCNP simulations. With the D-T neutron generator and HPGe detector set as the core of device, the modules, including reflector, moderator and shielding, etc., were optimized by a Signal-to-Noise Ratio (SNR) evaluation method. Moreover, the NIQAS device was set up for measuring the hazardous goods, and the type identification was discussed based on the established logical decision. Finally, a Graphical User Interface (GUI) was designed and the minimum detection time was further investigated. Highlights: The calculation method for Signal-to-Noise Ratio(SNR) in MCNP was introduced. The NIQAS device was designed and optimized based on the SNR evaluation method. 8 kinds of hazardous goods were identified for evaluating the good performance of device. The matched Graphical User Interface (GUI) was designed for NIQAS device.
