"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) - spectra 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 14 MeV and spectra extending to 32 MeV. The small-size samples (diameter of 15 mm) are irradiated at neutron flux up to 1011 n cm-2s-1 in this source. The determination of spectral flux at position of irradiated samples by the dosimetry-foil method is described in details. A summary of present and next program of neutron activation investigations relevant to the IFMIF is outlined." . "ENYGF 2011 - Extended Abstracts" . "[64F878C5404D]" . . "\u0160tef\u00E1nik, Milan" .
