3. Path-finding for triple-axis spectrometers

Tobias WEBER (Institut Laue-Langevin (ILL))

10/18/21, 4:40 PM

As part of our efforts in the field of autonomous instrument control, we present a path-finding algorithm and implementation for triple-axis spectrometers. Due to angular constraints in the instrument space, as well as from obstacles such as walls, not every (Q, E) coordinate point is accessible for the instrument. A careful mapping of the available positions is usually required before...

30. Benchmarking autonomous TAS experiments

Mario TEIXEIRA PARENTE

10/18/21, 5:10 PM

With the advancement of artificial intelligence and machine learning methods, autonomous approaches are recognized to have great potential for performing more efficient TAS experiments. In our view, it is crucial for such approaches to provide thorough evidence about respective performance improvements in order to increase acceptance within the community. Therefore, we propose a benchmarking...

6. The need for realistic simulations of phonon intensities in inelastic neutron and x-ray scattering – an experimentalist’s perspective

Frank Weber (Karlsruhe Institute of Technology)

10/18/21, 5:50 PM

The advent of inelastic neutron scattering in the middle of the last century enabled detailed studies of lattice vibrations, i.e. phonons, in condensed matter. Initially focused on simple structures [1,2], inelastic neutron scattering has been instrumental for our understanding of superconductivity in A15 compounds [3] and more recent conventional superconductors [4,5]. However, many materials...

21. Digital Twins and Virtual Experiments: developments and chances

Georg Brandl (Forschungszentrum Jülich, JCNS)

10/18/21, 6:30 PM

Recent experiences have highlighted that in order to ensure the continued success of neutron scattering as a method, user support must be improved not only at the facilities, but also while users are still in the planning, proposal-writing and preparation stages of an experiment.

Digital twins, which provide a virtual copy of neutron scattering instruments and their user interface(s), are an...
