Determination of neutron beam parameters of the DANCE flight path at LANSCE

ORAL

Abstract

Important characteristics of a moderated neutron beam include the time distributions of neutrons at a given energy (resolution function) and the absolute neutron flux. We will present a determination of the resolution function for the DANCE flight path at LANSCE. The determination is based on fitting resolved resonances from 1 eV to 1 keV using the SAMMY code. These results will be compared to Monte-Carlo calculations made using the MCNPX code with a detailed model of the target-moderator system and flight path.
