Global Characterisation of the GELINA Facility for High-Resolution Neutron Time-of-Flight Measurements by Monte Carlo Simulations
A comprehensive set of Monte Carlo simulations was performed with the MCNP5 code to provide a generic characterisation of the neutron and photon fluxes for time-of-flight measurements at all flight paths of the GELINA facility. Simulations were performed for the direct flux configuration (DFC, 10 keV-20 MeV) and the moderated flux configuration (MFC, 10 meV-1 MeV). Fluxes and flux energy spectra were obtained for, both neutrons and photons, while for neutrons detailed resolution functions and figures of merit were obtained, in addition. The validity
of the approach for the photon spectra is shown by comparison with a dedicated experiment. Also, an elaborate verification is presented of the validity of the neutron resolution function by comparison with measured capture and transmission data for 103Rh and 56Fe in the incident neutron energy range from 70 eV to 50 keV. This comprehensive overview will facilitate the planning and analysis of measurementsat the GELINA facility with an improved knowledge of its physical characteristics.
