Overview

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 Call 2020-B Results                   

The spring proposal call closed on February 26, 2020. A total of 751 instrument requests were submitted, 492 for SNS and 259 for HFIR.  At SNS, 177 proposals were awarded beam time, and 139 proposals were placed in alternate status with the potential to be approved if scheduling allows.  At HFIR, 134 proposals were awarded beam time, with 73 proposals placed in alternate status. Principal Investigators were notified on June 11th.  37% of proposals submitted to SNS were approved, and 52% of proposals submitted to HFIR were approved.

The General User Program (GUP) is currently limited to remote access experiments due to the COVID-19 pandemic. A date for resuming the onsite GUP has not been set.  Approved proposals will be run with remote user participation, or will be postponed until the GUP fully resumes.

The 2021-A Proposal Call is scheduled to close on September 16, 2020. Please check this page for updates.
