Event-Based Processing of Neutron Scattering Data

Abstract

Many of the world’s time-of-flight spallation neutrons sources are migrat- ing to recording individual neutron events. This provides for new opportu- nities in data processing, the least of which is to filter the events based on correlating them with logs of sample environment and other ancillary equip- ment. This paper will describe techniques for processing neutron scattering data in acquired in event mode which preserve event information all the way to a final spectrum, including any necessary corrections or normalizations. This results in smaller final errors, while significantly reducing processing time and memory requirements in typical experiments. Results with tradi- tional histogramming techniques will be shown for comparison.
