Abstract

A nuclear material detection system based on neutron/gamma-ray hybrid approach has been proposed for the container inspection at the sea port. The neutron from the inertial electrostatic confinement fusion source will be used for a fast pre-screening process. The quasi-monochromatic gamma-ray beam from the laser Compton Backscattering source will be used for an isotope identification for the precise inspection. Nuclear resonance fluorescence method will be employed for the isotope identification because of its high selectivity and high penetration for the shielding.
