Abstract
A fast-neutron time-of-flight spectrometer has been constructed for the purpose of measuring neutron differential cross sections of interest to the controlled thermonuclear reactor (CTR) program. The experimental facility provides the capability of measuring scattering cross sections of a few mb/sr to ∼5% absolute accuracy in the energy range from 6 to 15 MeV. Source neutrons are provided by the D(d,n)3He reaction. Scattered neutrons are detected at 28 angles between 25 and 160 deg in a massively shielded NE218 liquid scintillator located 4 m from the scattering sample. Absolute cross sections are obtained by normalizing to n-p scattering. Differential elastic and inelastic scattering cross sections are reported for 8.97-, 9.19-, 9.55-, 9.96-, 10.21-, 10.69-, 10.96-, 11.16-, 11.73-, 11.96-, 12.44-, 12.95-, 13.95-, 14.43-, and 14.93- MeV neutrons incident upon high-purity carbon. Monte Carlo simulation has been used to correct for finite source and sample effects. These data partially fill the 9- t...Keywords
