RESUMO

In 2002, an innovative neutron time-of-flight facility started operation at CERN: n_TOF. The main characteristics that make the new facility unique are the high instantaneous neutron flux, high resolution and wide energy range. Combined with state-of-the-art detectors and data acquisition system, these features have allowed to collect high accuracy neutron cross-section data on a variety of isotopes, many of which radioactive, of interest for Nuclear Astrophysics and for applications to advanced reactor technologies. A review of the most important results on capture and fission reactions obtained so far at n_TOF is presented, together with plans for new measurements related to nuclear industry.

RESUMO

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.
