Abstract: This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning across a one dimensional object of known dimensions. The model was then experimentally verified using an optical bench setup at ESS Utgård. The ultimate goal of this project was to accurately achieve a specified spatial resolution in a time-efficient manner.
