Neutron spectral distribution from a sealed-tube neutron generator by multiple-foil activation unfolding method

摘要

The spectral distribution of 14 MeV neutrons from a KAMAN sealed-tube neutron generator has been determined using threshold-energy monitor reactions in combination with the SULSA unfolding code, in which no input 'guess spectrum' is required except measured reaction rates of threshold monitor reactions. Result indicates that value of mean neutron energy determined in the present study compares well with the value obtained using the Nb-Zr ratio method. (C) 2003 Elsevier Science B.V.
