The U.S. Department of Energy (DOE) scientific user facilities – the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS) – are US Department of Energy sponsored research facilities open to researchers for advancing research in science and technology. HFIR and SNS, two of the world’s most advanced neutron scattering research facilities, offer thirty instruments covering a wide range of science and capabilities. Beam time is granted through the User Program and is free of charge with the condition researchers publish their results, making them available to the scientific community.
For Industries interested in learning more about proprietary research or how neutrons can help solve problems in industry, visit the Industrial Applications Program webpage.
Proposal calls are typically held bi-annually in the spring and fall. The 2025-B General User Proposal Call will close for submissions on Wednesday, February 26, 2025. Award letters for 2025-B submissions will be sent by April 25, 2025.
More details are provided on the proposal calls webpage.
Guidance regarding onsite visits can be found on the Plan Your Visit webpage.
