【Abstract】 Security check device for explosives’ detection based on Associated Particles Technique(APT)/Neutron Time of Flight(TOF) has been developed and tested.The device is remotely controlled from any PC-compatible computer.Inside is an APT neutron generator with a 3×3 matrix of semiconductor detectors of associated alpha-particles,the Shielding Protection of neutron and gamma-ray,Support Platform,Arrayed NaI(T1)-based detectors of gamma-rays,fully-digital data acquisition electronics,data analysis and decision-making software,transmission device and cover.The device is mainly used to detect explosives in luggage at check routeway,and it can also be "trained" to detect other hazardous materials,such as chemical/toxic/drug materials,if their chemical composition is in any way different from that of the surrounding materials.更多还原
