About us

Research and development of compact neutron system for practical use at anytime, anywhere RIKEN has developed accelerator-driven compact pulse neutron systems for practical use in industrial applications and non-destructive infrastructure inspection. They are called RIKEN accelerator-driven compact neutron source RANS and RANS-II. RANS has succeeded to develop non-destructive inspection methods with slow and fast neutrons. One is the visualization method of the corrosion and its related water painted steels and the analytical method of the quantitative estimation of the water movement in the painted steels, the other is the neutron engineering diffractometer for the texture evaluation and the austenite volume fraction estimation of iron and steel. The others are the fast neutron imaging applications. Novel scattered neutron imaging method to see through the fracture in the concrete slab has been successfully developed. The compact neutron systems are expected to be widely used on-site.
