Abstract
We are proposing a nondestructive detection and assay of nuclear material for purpose of nuclear security and safeguards. The system is based on a laser Compton scattered (LCS) gamma-ray source and nuclear resonance fluorescence (NRF). Using energy-tunable and mono-energetic gamma-ray from a LCS source and isotope-specific photo-nuclear reaction of NRF, we can detect and assay nuclides in a nondestructive manner. We have launched a research and development program of the LCS gamma-ray NDA systems, which includes demonstration of LCS photon generation from an ERL, establishment of measurement methods for highly radioactive samples, benchmark of Monte Carlo code. In this paper, we present status of the R&D program.
