Abstract

High resolution neutron spin echo (NSE) spectroscopy is one of the most powerful techniques to study the dynamics of soft matter. For NSE spectroscopy at a pulsed source, the data reduction and analysis present new challenges and opportunities as compared to a steady (reactor) source experiment. We present a data reduction framework which extracts information of all time channels and detector images, grouping the results into S(q,t) for a series of q and t, also across different instrument settings (different q). This strategy helps to get the most out of an experiment (a set of scans at different diffraction angles) and also provides appropriate reporting on the quality of the evaluation. The same software is also capable of dealing with reactor source data, where no time-of-flight information is present.
