Measurement of the high energy neutron flux on the surface of the natural uranium target assembly QUINTA irradiated by deuterons of 4 and 8 GeV energy

Popis výsledku v původním jazyce

Experiments with the natural uranium target assembly 'QUINTA' exposed to 4 and 8 GeV deuteron beams of the Nuclotron accelerator at the Joint Institute for Nuclear Research (Dubna) are analyzed. The reaction rates of Al-27(n,yl)Na-24, Al-27(n,y2)Na-22 and Al-27(n,y3)Be-7 reactions with effective threshold energies of 5, 27, and 119 MeV were measured at both 4 GeV and 8 GeV deuteron beam energies. The average neutron fluxes between the effective threshold energies and the effective ends of the neutron spectra (which are 800 or 1000 MeV for 4 or 8 GeV deuterons) were determined. The evidence for the intensity shift of the neutron spectra to higher neutron energies with the increase of the deuteron energy from 4 GeV to 8 GeV was found from the ratios of the average neutron fluxes. The reaction rates and the average neutron fluxes were calculated with the MCNPX 2.7 code.
