Neutron Scattering Facilities

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.
