| 520 | _ | _ | |a Complementary to Prompt Gamma Neutron Activation Analysis (PGNAA) with cold or thermal neutrons, the FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) instrument installed at Heinz Maier-Lebnitz Zentrum (MLZ), enables non-destructive analysis of large objects via the detection of prompt gamma rays emitted in inelastic scattering or other fast-neutron-induced reactions [1-6]. Besides creating a modern and comprehensive catalogue of (n,n’γ) reactions another major objective is to optimize the instrument design with regard to its efficiency and sensitivity. As a certain fraction of fast neutrons always scatters from the sample towards the high-purity germanium (HPGe) detector, a filter material must be placed in the collimation tract of the outer shielding to reduce undesired background as well as to prevent saturation of the detector due to higher gamma-ray fluxes in thick samples.In this talk, originally intended to be held at the 2nd PhD days 2022, the final results of filter simulations performed with MCNP6 are given. Important results from the last talk are repeated. This time a major focus is set on the gamma-ray performance, i.e. how the filter material influences the gamma-ray flux and efficiency. The main results are also illustrated on a print poster that will be presented in the following discussion. |
