Abstract:

A system has been designed and constructed for high accuracy neutron cross section measurements using pulsed beam time-of-flight techniques. The detection system has been used to obtain neutron scattering cross sections for Al, Si, Fe, Ni, and Co at 9.0 MeV incident neutron energy and to obtain a survey of neutron scattering by Carbon from 7 to 9 MeV incident energy. The cross sections have a normalization uncertainty or accuracy of about 5, precision of 2-3 for strongly excited groups, and a precision of 5-10 for weakly excited groups. The report presents detailed design criteria for the detection system, and a description of detector shielding constructed for the measurements. It also contains a study of the data corrections which most strongly influence the accuracy of results. Modified author abstract
