Neutron Scattering Facilities

This activity supports the operation of two neutron scattering facilities, which are unique and effective tools for probing the structure of matter. Neutron scattering is particularly well-suited for determining the atomic positions of both light and heavy atoms in a solid and thermal fluctuations in these positions. In addition the neutron scatters from magnetic moments in the material thus providing information on the magnetic structure as well. The neutron energy is well-matched to that of elementary atomic and magnetic excitations (spin waves and phonons) in a material and, via inelastic scattering, can provide data crucial for understanding basic phenomena in superconductors, magnetic systems, and multi-ferroic materials.

Spallation Neutron Source (SNS)

at Oak Ridge National Laboratory

The SNS is a next-generation spallation neutron source for neutron scattering that is currently the most powerful neutron source in the world.

High Flux Isotope Reactor (HFIR)

at Oak Ridge National Laboratory

The HFIR facility is the United States’ highest flux reactor-based neutron source, and is a major neutron scattering user facility as well as the world’s leading source of elements heavier than plutonium for research, medicine, and industrial applications.
