Accurate simulations of magnetic excitations in the neutron simulation package McStas

Journal of Applied Crystallography, EarlyView.
We present an accurate algorithm for simulating neutron scattering from spin waves in the ray‐tracing package McStas.An algorithm for the accurate simulation of neutron scattering from magnetic excitations has been developed and implemented as new component for the neutron ray‐tracing software McStas.

Design of polychromatic focusing optics for neutron reflectometers: rethinking REFocus optics

Journal of Applied Crystallography, EarlyView.
REFocus optics, employing an elliptical mirror and higher‐order reflections, enable rapid wide‐Q‐range neutron reflectometry at reactor sources, achieving up to 100‐fold faster measurements compared with conventional methods.Neutron reflectometry is a widely used non‐destructive technique for analyzing surface and interfacial structures. In this study,

Towards machine‐learning‐based on‐the‐fly analysis of neutron reflectometry

Journal of Applied Crystallography, EarlyView.
An automated machine‐learning‐based processing and analysis workflow for neutron reflectometry data is presented. The approach has been successfully used for on‐the‐fly analysis during an experiment at the Institut Laue–Langevin (Grenoble, France) and can be adapted to work at other neutron facilities seeking to enable real‐time feedback‐driven ...

Spin excitations near the pressure‐induced antiferromagnetic transition in SrCu2(BO3)2

Journal of Applied Crystallography, EarlyView.
Inelastic neutron scattering on SrCu2(BO3)2 at 4.2 GPa reveals dispersive spin excitations in the antiferromagnetic phase, consistent with linear‐spin‐wave theory and highlighting the key role of interlayer coupling.SrCu2(BO3)2 is a frustrated quantum magnet which realizes the Shastry–Sutherland model. The system exhibits a sequence of pressure‐induced

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,
