Nondestructive isotope-specific assay system using nuclear resonance fluorescence has been developed at JAEA. In this system, intense, mono-energetic laser Compton scattering (LCS) -rays are generated by combining an energy recovery linac (ERL) and laser enhancement cavity. As technical development for such an intense -ray source, we demonstrated generation of LCS -rays using Compact ERL (supported by the Ministry of Education, Culture, Sports, Science and Technology) developed in collaboration with KEK. We also measured X-ray fluorescence for elements near iron region by using mono-energetic LCS -rays. In this presentation, we will show results of the experiment and future plan.
