RIKEN accelerator-driven compact neutron source (RANS) has been developed and provided neutrons for industrial use. The proton linac of 7 MeV with the maximum average current 100 μA, pulse width 10-180 μs, repetition frequency 20-200 Hz is used with long-life Be target for such practical use in the field of manufacturing. Corrosion in the painted steels are visualized, neutron imaging and neutron diffraction technique have developed with compact neutron source. Non-destructive visualization inside thick concrete slab has been realized for the social infrastructure safety with compact neutron source system.
