FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) is a new instrument at MLZ. [1]

The instrument consists of an electro-mechanically cooled HPGe detector connected to a digital spectrometer for data acquisition and is surrounded by a complex shielding. [2]

FaNGaS utilisses fission neutrons at the SR-10 neutron beam tube to induce gamma radiation for chemical analysis. The particularly large beam diameter at SR-10 allows for the irradiation of large objects. Non-destructive qualitative and quantitative elemental analysis is performed by using prompt gamma irradiation that is induced by fission neutrons via nuclear reactions, such as (n,n’), (n,2n), (n,p) and (n,α).
