Spallation Neutron Source

SNS site, Spring 2012

The 80-acre SNS site is located on the east end of the ORNL campus and is about a three-minute drive from her sister neutron facility, the High Flux Isotope Reactor. The rectangular building in front is the ORNL Guest House. (larger image)

SNS is a one-of-a-kind research facility that provides the most intense pulsed neutron beams in the world for scientific research and industrial development. SNS produces neutrons with an accelerator-based system that delivers short (microsecond) proton pulses to a target/moderator system, where neutrons are produced by a process called spallation. State-of-the-art experiment stations provide a variety of capabilities for researchers across a broad range of disciplines, such as physics, chemistry, materials science, and biology.

With its more intense, brighter source of neutrons and world-class instrumentation, SNS provides the neutron scattering community with unprecedented research opportunities. SNS allows for measurements of greater sensitivity, higher speed, higher resolution, and in more complex sample environments than have been possible at existing neutron facilities.

SNS is available to researchers from all over the world with varying degrees of experience. Submitted research proposals are reviewed by independent scientists from within the neutron scattering community, and the most promising ones are chosen. Find out more about how to conduct research at SNS.
