JAEA, QST, and University of Hyogo are developing a nuclear material detection technique that utilizes a measurement method of nuclear resonance fluorescence gamma-ray scattering induced by laser Compton scattering gamma-ray beams, under the subsidiary for "promotion of strengthening nuclear security or the like" of MEXT. So far, experimental apparatus, a laser system, gamma-ray detectors, data acquisition systems, and so on, are prepared for a demonstration experiment to be performed at NEW SBARU facility of University of Hyogo. An imitated nuclear material sample hidden in a shield will be placed on an automatic stage. This presentation overview the purpose of this program, preparation status, plan of demonstration experiments and a workshop.
