Development of a neutron resonance transmission analysis using a laser driven neutron source

Ito, Fumiaki*; Koizumi, Mitsuo; Takahashi, Toon; Suzuki, Satoshi*; Lee, J.

Neutron Resonance Transmission Analysis (NRTA) is one of the active neutron NDA techniques being developed under the subsidiary for "promotion of strengthening nuclear security or the like" of MEXT. A short pulse neutron source is required to apply NRTA method to an accurate measurement of nuclear materials. A laser driven neutron source (LDNS) is considered to be such a neutron source. A study of applicability of LDNS to NRTA, and neutron detector development are in progress. The Monte Carlo simulation code PHITS was used for designing a neutron generation part, a neutron flight path, and a neutron detector system.
