Abstract

The detection of hidden special nuclear materials (SNMs) is important issue for nuclear security. For this purpose, we have been developing an active neutron-based interrogation system combined with a D-D fusion neutron source, which is a compact discharge-type fusion neutron source called IEC (Inertial-Electrostatic Confinement Fusion) device and provides pulsed neutrons of 2.45MeV. The neutron noise analysis method and the detection of high energy fission neutron spectrum are employed for detection of SNMs.
