    Abstract

    Non-destructive detection and assay of nuclear materials is one of the most critical issues for both the management of nuclear waste and the non-proliferation of nuclear materials. We use laser Compton scattered (LCS) γ-ray beams and the nuclear resonance fluorescence (NRF) for the non-destructive detection of radioactive materials. Quasi-monochromatic and energy-tunable LCS γ-ray beams help improve the signal-to-noise ratio during NRF measurements. We developed the conceptual design of a high-flux γ-ray source with an energy-recovery linac, which produces a γ-ray beam at the flux of 1013 photons / s . In this paper, we discuss the execution of simulation studies using a Monte Carlo code, results of a proof-of-principle experiment for isotope detection, and the status of the development of LCS X-ray and γ-ray facilities.
