Detection of concealed Special Nuclear Material using Nuclear Resonance Fluorescence technique

Detection method based on nuclear resonance fluorescence (NRF) technique targeting concealed special nuclear material (SNM) has been discussed. Customized DAQ system has been developed to handle high rate events in NRF measurements by implementing real-time DSP on fast ADC and FPGA chip. Experiments have been setup for feasibility study utilizing a 3 MeV Van de Graaff accelerator. NRF peaks from various samples have been observed using both HPGe detector and lanthanum halide scintillation detector.
