Inelastic neutron scattering is a powerful technology to measure the lattice dynamics of materials, which is essential to understand the thermal transport properties and other phonon-related properties. The realization of obtaining a sufficient amount of effective data within a limited time is a major demand facing the development of the current inelastic scattering technology. Here, we...

The importance of scientific computing and data management for harnessing the full potential of the European Spallation Source (ESS) was recognized early on in the ESS’s design phase. The ESS Data Management and Software Centre (DMSC) was therefore already established at the foundation of ESS and charged with providing the scientific computing tools and services that users need from proposal...

To simulate inelastic neutron scattering in a single crystal, the algorithm needs to sample a high dimensional distribution. The numerical difficulties are twofold. To start with, the memory footprint of such distribution is typically challenging for mainstream computers to handle. Secondly, the energy and momentum resolutions of the sampled results may not optimised, if the distribution is...

The magnetic pair distribution function (mPDF) analysis of neutron total scattering data has recently emerged as a powerful method for investigating the local magnetic correlations in materials. Similar to the atomic pair distribution function (PDF) method, the mPDF utilizes the Fourier transform of the magnetic neutron scattering cross section to obtain information about magnetic structures...
