ORNL hosts two of the world’s most powerful sources of neutrons for research: the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS). The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tenn., produces the most intense pulsed neutron beams in the world. Neutron/ X-rays Complimentary For Short-range Order Measurements • Chemical order diffuse scattering proportional to contrast (f A-f B)2 • Neutron scattering cross sections – Vary wildly with isotope – Can have + and - sign – Null matrix – Low Z , high Z comparable • X-ray scattering cross section – Monotonic like Z2 National School on Neutron and X-ray Scattering : June 11-25, 2011 Oak Ridge National Laboratory, Oak Ridge, TN Argonne National Laboratory, Argonne, IL 2013-08-21 · Spallation Neutron Source (SNS) Neutron scattering was pioneered at ORNL in 1946 by Clifford G. Shull. Shull went on to be a co-recipient of the 1994 Nobel Prize in Physics for “the development of the neutron diffraction technique”.

On the way, it has helped researchers deliver practical breakthroughs and new scientific knowledge in climate, materials, nuclear science, and a wide range of other disciplines. Neutron scattering grew from the nuclear science of the Manhattan Project during the 1940s at what is now Oak Ridge National Laboratory (ORNL). Clifford Shull was awarded half of the 1994 Nobel Prize in Physics for research he conducted with the late Ernest Wollan leading to neutron The prototypes were tested on neutron scattering instruments at ORNL’s Spallation Neutron Source and High Flux Isotope Reactor, both DOE User Facilities located at ORNL.
