| Research Abstract |
A nondestructive assay system for security management application is proposed. We employ a compact electron linac as an X-ray source and 14.1MeV neutron source. The combination of these novel technologies realizes a fast security scanning system. Due to a need for security screening instruments capable of detecting explosives and nuclear materials there is growing interest in neutron generator systems suitable for field use for applications broadly referred to as active neutron interrogation. The system incorporate hermetically-sealed particle accelerator tubes designed to produce fast neutrons using deuterium-tritium (En=14.1 MeV) fusion reactions. Employing next-generation features including advanced sealed-tube accelerator designs, all-digital control electronics and innovative housing configurations these systems are suitable for many different uses. The neutron source is used for active neutron The 950 keV portable X-band (9.4 GHz) linear accelerator (Linac) provides on-site high-energy X-ray inspection, including material recognition up to a certain precision. We have developed an X-band Linac system and have achieved the maximum 950 keV X-ray by using the low-power magnetron (250 kW) in a 2-ms pulse length. We have already experimentally verified the dual-energy X-ray material recognition with and without an energy filter. Further, the array of the scintillator detector for dual energy X-ray measurement without the energy filter is numerically analyzed and designed for much quicker measurements. Updated results will be presented.
