Simulating neutron transport in long beamlines at a spallation neutron source using Geant4

, 2020
The transport of neutrons in long beamlines at spallation neutron sources presents a unique challenge for Monte-Carlo transport calculations. This is due to the need to accurately model the deep-penetration of high-energy neutrons through meters of thick

Quantitative neutron characterization of dislocation-nanoprecipitate synergistic strengthening in additively manufactured FeCoNiAlTi high-entropy alloy with ultrahigh yield strength

Journal of Materials Research and Technology
Introducing dislocations and nanoprecipitates is an effective strategy to strengthen alloys, but reliable bulk quantification of dislocation density and coherent nanoprecipitate content remains challenging.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Development of a neutron texture analysis reduction pipeline in Mantid

Journal of Applied Crystallography, EarlyView.
An experimental planning and data processing pipeline for spatially resolved neutron texture analysis has been implemented within the Mantid framework. The workflow processes time‐of‐flight neutron diffraction data to generate experimental pole figures, enabling non‐destructive quantitative texture analysis of materials and components with complex ...

Stroboscopic neutron scattering measurements using Raspberry Pi‐based sample environment event mode

Journal of Applied Crystallography, EarlyView.
An inexpensive device based on a Raspberry Pi can give neutron scattering instruments the ability to carry out stroboscopic measurements in a relatively simple and flexible fashion. Stroboscopic measurements can be used to study fast kinetic processes in condensed matter systems.An inexpensive single‐board computer (Raspberry Pi 5) was employed to ...
