Description

Extracting scientific results from neutron experiments requires a challenging multiple-step treatment of the data, starting from the reduction and followed by the analysis. In order to simplify some of the repetitive procedures, automated and real time data reduction based on Mantid [1] has been tested at the Spallation Neutron Source and ISIS [2]. The second stage, the data analysis, can also be run “live” during the experiment in a simplified way to provide visual and numerical feedback on the quality of the acquired data. Thus, the real-time analysis enables the user to tune the running experiment either manually or automatically via feedback to the control system.
The European Spallation Source ERIC (ESS) will generate a very intense long pulse to feed state-of-the-art instruments. In order to fully harness the potential of this powerful neutron source and ensure that a user can leave the facility with useful results, the ESS aims to give user the option to analyze data live during a running experiment for some of its high-throughput instruments.
Here we report on the proof-of-concept for automated analysis of powder diffraction data and also small angle neutron scattering data, based on Fullprof [3] and SasView [4], respectively. These results are parts of an automated data processing workflow, i.e. collecting, reducing, analyzing, developed at the Data Management and Software Centre of the ESS [5].
