The cyclotron-based fast neutron sources of the white- and quasi-monoenergetic spectra are operated at the NPI Rez Fast Neutron Facility utilizing the variable proton (up to 36 MeV) and deuteron (up to 20 MeV) beams delivered by the U-120M isochronous cyclotron and target stations with the Be(thick), D2O(thick), and Li(C) neutron production targets. The upgraded beryllium target station provides the high intensity neutron field of broad spectra up to 33 MeV with mean energy of 14 MeV. The energy range corresponds to the main energy part of IFMIF (International Fusion Material Irradiation Facility) neutron spectrum. This IFMIF-like source is appropriate for the radiation hardness tests of materials and electronics, validation of activation cross-section data within the fusion relevant research programs, and fast neutron activation analysis experiments. At the NPI CAS, the neutron field of p + Be source reaction was studied for proton beam energy of 35 MeV using the multi-foil activation technique. The modified version of SAND-II deconvolution tool was used for neutron spectrum reconstruction up to 33 MeV (i.e. energy region with a lack of experimental neutron spectral data).
