The NPI cyclotron-based fast neutron facility

Popis výsledku v původním jazyce

For validating activation cross-section data in the energy range relevant to IFMIF (International Fusion Material Irradiation Facility), the fast neutron sources were developed utilizing the NPI variable-energy cyclotron U-120M. Novel concept of source reaction was investigated for a generation of the white - (IFMIF-like) - spectrum on NPI cyclotron. The deuteron break-up process induced by 37 MeV protons on flowing heavy water target was found to produce neutrons with high intensity, mean energy of 14MeV and spectrum extending to 32 MeV. The small-size samples (diameter of 15 mm) are irradiated at neutron flux up to 10(11) n/cm(2)/S in this source. The quasi-monoenergetic neutron field in the energy range from 20 to 35 MeV is produced using standardLi-7(p,n) reaction on thin (carbon backed) lithium foil. The p-Li source produces neutron flux up to 10(9) n/cm(2)/s. The present work deals with methodical, technical and functional characteristics of p-D2O and p-Li-7 neutron sources.
