Abstract :
A study of a non-destructive inspection system for hidden special nuclear materials in the cargo container at the sea port has been carried out under a promotion of Japan Science and Technology. This inspection system consists of an active neutron detection method for a fast screening purpose and a nuclear resonance fluorescence (NRF) method for isotope identification. The inertial electrostatic confinement fusion device has been developed for a neutron source and two neutron detection methods, the Feynman-alpha method and high energy neutron detection method, have been examined to realize the fast screening system. Generation of a quasi-monochromatic gamma-ray beam from the laser Compton Backscattering by using a compact microtron electron accelerator and an NRF experiment on uranium target using a new type of scintillation detector, LaBr3(Ce), has been studied to realize the isotope identification system.
