Abstract
Elastic and inelastic neutron differential cross sections are measured at the University of Kentucky Accelerator Laboratory (www.pa.uky.edu/accelerator/) at incident energies in the fast neutron region. The labo- ratorys facilities and instrumentation will be described and our measurement and analysis procedures outlined. Many corrections are required for neutron scattering experiments and the analysis utilizes information from many other cross section data sets and model calculations. Exploring and understanding the limitations of the foundational information and procedures are important for controlling the accuracy of the cross section results. We are examining the limitations in neutron detection efficiency, the normalization of (n,n � γ) cross sections, background reduction, spectrum stripping techniques, and attenuation and multiple scattering corrections. The resulting differential cross sections provide information on the compound elastic and coupled channels reaction mechanisms important for advanced reactor designs.
Highlights
The USDOE Advanced Fuels program funds R&D of innovative generation LWR and future fast systems
The laboratory is designed for the fast neutron region a region that is important for both pure and applied nuclear physics
A specialized fitting code which is guided with Monte Carlo predicted response functions seems merited
Summary
The USDOE Advanced Fuels program funds R&D of innovative generation LWR and future fast systems. Recent evaluations revealed there are significant disagreements in cross section between the nuclear libraries, especially above 1 MeV where there is a critical lack of measurements
