FaNGaS
Fast Neutron-induced Gamma-ray Spectrometry
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 utilizes fission neutrons at the SR10 neutron beam port to induce gamma radiation for chemical analysis. The particularly large beam diameter at SR10 allows for irradiation of large objects. Non-destructive qualitative and quantitative elemental analysis is performed by use of prompt gamma irradiation that is induced by fission neutrons via nuclear reactions, such as (n,n’), (n,2n), (n,p) and (n,α).3
