Cadmium and gadolinium spectral filters comparison

Knowledge of neutron energy spectra is very important because neutrons with various energies have a different material impact or a biological tissue impact. This paper presents results of the neutron energy distribution inside the experimental setup which is located at Brno University of Technology in Brno, Czech Republic. The goal of the experiment was to obtain more precise information about the neutron energy distribution when the thickness of moderator is changing. The set of indium activation detectors, cadmium and gadolinium spectral covers were used to the investigation of neutron energy distribution. The results of the measurement provide information about the change of neutron energy distribution in the experimental setup.
