Spectral flux of the p-7Li(C) quasi-monoenergetic neutron source measured by proton-recoil telescope
Original language description
The cyclotron-based fast neutron source at NPI produces mono-energetic neutron fields up to 35 MeV neutron energy using the p+7Li(carbon backing) reactions. To be applied for activation cross-section measurements, not only the intensity of neutron peak,but also the contribution of low-energy continuum in the spectra must be well determined. Simulations of the spectral flux from present source at a position of irradiated samples were performed using CYRIC TOF-data validated in the present work against LA150h by calculations with the transport Monte Carlo code MCNPX. Simulated spectra were tested by absolute measurements using a proton-recoil telescope technique. The recoil-proton spectrometer consisted of a shielded scattering chamber with polyethyleneand carbon radiators and the ?E 1 -?E 2 -E telescope of silicon-surface detectors located to the neutron beam axis at 45° in the laboratory system. Si-detectors were handled by usual data acquisition system. Dead
