Neutron spectrometry developments

We have made new improvements on neutron spectrometry systems used for radiation protection applications. Our work has resulted in several data-reduction programs suitable for small computers. We have also measured spectra at the Standards and Calibration Facility for various source/moderator configurations, and have made Monte Carlo calculations which resulted in better multiple-scattering and edge-effect corrections. For neutrons with energies below 1 MeV, we confirmed our predicted light-output values. Finally, we have refined our use of the combined liquid scintillator/multisphere system. 13 refs., 6 figs. (DT)
