The GELINA facility in Geel, Belgium is a neutron source renowned for its fast time resolution of 2ns [1]. Its GAINS spectrometer focuses on neutron inelastic cross-sections, with this process of scattering being a common occurrence in fission reactor cores. It currently consists of HPGe detectors, with remarkable energy resolutions. However, there has been interest in upgrading the spectrometer with the addition of detectors with relatively higher efficiences. In this research, the suitability of the scintillator detector BaF2 for neutron cross-section determination was characterized. Using the trapezoidal FIR energy filter approach, the energy resolutions at different energies were determined with 60Co and 22Na radioactive sources. The resolutions were then compared to literature values, followed by an analysis of the scaling behaviour with respect to the incident photon energy.
