Oak Ridge National Laboratory (ORNL) is at the US epicenter for one of the most powerful techniques exploring the nature of materials and energy—neutron scattering. ORNL hosts two of the world’s most powerful sources of neutrons for research: the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS) . Neutrons have no electrical charge, which allows them to easily and safely pass through a sample, revealing information about the material’s structure and properties. Neutron scattering is used in many industries—automotive, aerospace, steel, defense, industrial materials, energy storage, data storage, biomedicine, and others—to address the 21 st century’s major scientific challenges. Discoveries fueled by neutron research at ORNL help scientists answer big science questions and spur countless innovations such as stronger glass for mobile devices, drugs that more effectively treat diseases, more reliable aircraft and rocket engines, cars with better gas mileage, improved armor for the military, and batteries that are safer, charge faster, and last longer. 607 Scientific Publications in FY23* 1,177 Total Unique Users in FY23 85,442 Hours of Beamtime in FY23 1,167 Total Experiments in FY23 *607 total publications including 507 peer-reviewed journal articles Contact Jens_Dilling.png Jens Dilling Associate Laboratory Director Neutron Sciences Directorate dillingj@ornl.gov Research Highlights Large Linear Magnetoelectric Effect in DyCrO4​ See AllTop Science Achievements in 2023 3-Source Strategy: High Flux Isotope Reactor, Spallation Neutron Source, Second Target Station High Flux Isotope Reactor Operating at 85 MW, HFIR provides one of the highest steady-state neutron fluxes of any reactor in the world for materials research.
