Description
Neutron analytical methods are indispensable tools for non-destructive elemental analysis of materials or items of various origins (geological, environmental, biological, cultural, archeological and industrial). Fast neutron inelastic scattering brings analytical capabilities to a new level, allowing to analyze thick and dense samples thanks to higher incident energy of neutrons via (n,n’,gamma) reactions. FaNGaS (Fast Neutron Gamma-ray Spectrometry) instrument installed at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching is a new instrument that uses fission neutrons delivered by the SR10 beam tube of the FRM II reactor allowing measurement of small to large samples up to 400 cm3 in volume. Another important application of FaNGaS instrument is measurement of partial prompt gamma-ray production cross-sections of (n,n’,gamma) reactions, contributing to extend and improve nuclear data. Coupling of FaNGaS with advanced fast neutron techniques such as fast neutron imaging and transmission techniques broadens the range of analytical capabilities for qualitative and quantitative analysis of nonhomogeneous samples. Coupled with fast data processing algorithms based on modern machine learning tools large measured data streams from bulk and voluminous samples can be analyzed online, making such fast neutron-based analytical technology promising in a wide range of tasks for industrial applications (e.g. ore, coal, magnetic material waste streams etc).
