Abstract

The use of Bonner spheres to characterise radiation fields is abundantly documented in the literature. This study, carried out using the state-of-the-art Monte Carlo code MCNPX and the deconvolution program MAXED, aims to characterise the RPI epithermal neutron beam using of a set of Bonner spheres of different radii surrounding a 3He detector. The energy range of interest in this study covers from thermal to 10 MeV. This purely computational study aims to assess the feasibility of using the method previously mentioned to improve the knowledge of the energy and intensity characteristics of the epithermal beam.
