Trends and Perspectives in Neutron Instrumentation:
Advanced simulation and open source software in neutron scattering

29 October - 1 November 2018, Tutzing, Germany



As the materials being studied by neutron techniques become more complex, the link between computer modeling and experimental data is becoming increasingly important. However, the access to the most suitable and state-of-the-art modeling techniques is generally limited by an individual experimental scientist’s lack of modeling experience and local expertise. This creates an energy barrier to the most suitable and detailed data analysis that is often not overcome.At the same time the amount of data generated and to be processed has and will increase steadily. Modern detector technology, time-of-flight experiments, event mode recording, xD-data sets or 3D-tomography require powerful data storage, transfer and reduction software for presentation and analysis of collected data. Neutron scattering, and in particular inelastic neutron scattering is very amenable to computer modeling. Furthermore, in the majority of cases, the interpretation of experimental spectra is not possible without the use of computer simulations. Density Functional Theory (DFT) calculations, molecular modelling, Monte-Carlo simulations, complex more dimensional fitting procedures and sophisticated algorithms are developed to combine theory and experiment. Depending on the used method available software ranges from fully standardized programs to very specialized tools for specific applications. Standard software can be used often everywhere with resources to be downloaded from the internet, while specialized tools are only applicable at individual facilities or groups, working on the particular problem.

General software platforms for the neutron data analysis and simulation that supports high-performance computing are on the way.
This workshop will bring together experts with neutron scattering users to review modeling techniques and provide the opportunity for the community to discuss current limitations, new capabilities, and future developments. It aims at highlighting recent approaches and developing ideas on the combining simulation and experiment with appropriate software and simulation tools.

The topics will include

  • Modelling and Simulation
  • Micromagnetic modelling
  • DFT and spin waves
  • Protein dynamics
  • Membrane structure and dynamics
  • Polymers
  • Crystal structure determination
  • SANS and reflectometry
  • Virtual experiments
  • Monte Carlo ray tracing and instrumentation
  • Data Handling and data reduction
  • Open source software

The conference is organized by the Jülich Centre for Neutron Science (JCNS), Forschungszentrum Jülich.
