Název v původním jazyce

Neutron activation experiments on chromium and tantalum in the NPI p- Li-7 quasi-monoenergetic neutron field

Popis výsledku v původním jazyce

The work aims to make the study of neutron activation cross section data up to 35 MeV neutron energy using the reaction Li-7(p,n). This reaction produces the high-energy quasi-monoenergetic neutrons with some tail to lower energies. The cross section data for neutron energies higher than 20 MeV are not well known. The data are needed for the development of the International Fusion Material Irradiation Facility (IFMIF) to test materials for fusion power plants technology and for the comparison to nuclearreaction models as well. The variable-energy proton beam of NPI cyclotron is used for the production of the quasi-monoenergetic neutron field using the thin lithium target. The carbon backing for the Li target is utilized as the beam stopper. The stableoperation of the source is achieved under cooling of the Li foil and the carbon backing separately. The system permits to produce neutron flux density of about 10(9) n/cm(2)/s in peak at 30 MeV neutron energy.
