Abstract
An inelastic neutron scattering facility consisting of a DT neutron generator and a HPGe detector was used for metallic material analysis. The facility model was optimized based on Monte Carlo simulations. Performance of modified facility was tested through various metallic elements measurements. The results showed that the mass detection limits (MDL) of different elements were improved after optimization. Quantitative analyses of Fe and Cr in stainless steel sample were then conducted to evaluate the performance of alloy measurement. Calibration curves were obtained through measuring the reference samples. The contents of Fe and Cr in an unknown sample were determined by the calibration curves and the results were in good agreement with those obtained by X-ray fluorescence method.
