High-Power p(35)-Be White Neutron Source for Activation Experiments at NPI

Popis výsledku v původním jazyce

The cyclotron based neutron generators of the white- and quasi-monoenergetic spectra are operated at the NPI Řež Fast Neutron Facility utilizing the variable-energy proton beam (up to 37 MeV) and the D2O (flow), Be (thick), and 7Li(C) target stations. The intensity and the energy range of the produced neutron fields are suitable for the integral and differential validation of the neutron cross-sections within the ADTT- and fusion-relevant (IFMIF) research programs. In the neutron activation experiments,the irradiated samples are usually fixed in the vicinity of the source target, and the dimensions of the target and samples are comparable with the target-to-sample distance. Therefore, to determine the neutron spectral flux at the sample position fromthe cross-section data, a simple employment of the 1/r2 law is not relevant. Instead, the MCNPX calculations are required to take into account the space and energy integration of neutron yield observables over the geometry arrangement of
