The spatial distribution of neutron fluences in the extended uranium target (“Quinta” assembly) irradiated with 0.66 GeV proton, 4 AGeV deuteron and carbon beams was studied using the reactions with different threshold energy (Eth). The data sets were obtained with 59Co samples. The accumulation rates for the following isotopes: 60Co (Eth 0 MeV), 59Fe (Eth 3 MeV), 58Co (Eth 10 MeV), 57Co (Eth 20 MeV), 56Co (Eth 32 MeV), 47Sc (Eth 55 MeV), and 48V (Eth 70 MeV) were measured with HPGe spectrometer. The experimental accumulation rates were compared with the predictions of the simulations with Geant4 code. Substantial difference between the reconstructed and the simulated data for the hard part of the neutron spectrum was analyzed.
