| Abstract |
The experiment was performed on a pulsed neutron source of the "Neutron" research bench, being created at the U-70 accelerator at National Research Center "Kurchatov Institute" - IHEP, Protvino. Neutrons were generated by the 50 GeV proton beam in the special converter. As a measurement method, neutron activation analysis was used with a set of threshold activation detectors made of C, Al, Nb, In, Bi materials. The neutron energy thresholds of these detectors are in the range from 1 MeV to 75 MeV. The aluminium activation foils were used to calculate the absolute values of the proton quantities in the exposures. The results of measurements and calculations are presented in the form of the following functionals: nuclides activity of threshold reactions in detectors at the end of the exposure; reaction rate; neutron fluences with energies greater than the threshold. To estimate these values, the spectra of neutrons, protons and pions were calculated using the particle transport codes MARS and HADRON with the FAN15 as a low-energy block. It was found that neutrons dominate up to 100 MeV, and the charged hadrons contribution to the total reaction rate for a particular nuclide formation can range from 4% to 46%.
