Description

Neutron analytical methods are indispensable tools for non-destructive elemental analysis of materials or items of various origins. Prompt Gamma Analysis based on Inelastic Neutron Scattering (PGAINS) brings analytical capabilities to a new level, allowing to analyze thick and dense samples thanks to higher incident energy of neutrons via (n, n’, g) 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’, g) reactions, contributing to extend and improve nuclear data. Possibility to couple PGAINS method with advanced fast neutron techniques such as fast neutron imaging and transmission techniques broadens the range of analytical capabilities for qualitative and quantitative analysis, making such analytical technology promising for a wide range of tasks in geological, environmental, cultural, archeological and industrial applications.
