NEUTRONS FOR NEW DISCOVERIES AND SOLUTIONS
Breakthroughs in medicine, energy, technology, and industry follow advances in
the understanding of materials. Oak Ridge National Laboratory (ORNL) is at the
US epicenter for one of the most powerful techniques exploring the nature of
materials and energy—neutron scattering.
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).
Neutrons have no electrical charge, which allows them to easily and safely pass
through a sample, revealing information about the material’s structure and
properties.
Neutron scattering is used in many industries—automotive, aerospace, steel,
defense, industrial materials, energy storage, data storage, biomedicine, and
others—to address the 21st century’s major scientific challenges.
Discoveries fueled by neutron research at ORNL help scientists answer big
science questions and spur countless innovations such as stronger glass for
mobile devices, drugs that more effectively treat diseases, more reliable
aircraft and rocket engines, cars with better gas mileage, improved armor for
the military, and batteries that are safer, charge faster, and last longer.

3-SOURCE STRATEGY:
HIGH FLUX ISOTOPE REACTOR, SPALLATION NEUTRON SOURCE, SECOND TARGET STATION
* HIGH FLUX ISOTOPE REACTOR
Operating at 85 MW, HFIR provides one of the highest steady-state neutron
fluxes of any reactor in the world for materials research.
* Operating Status: Reactor is Off
*
* SPALLATION NEUTRON SOURCE
SNS is the most powerful pulsed neutron source in the world for materials
research.
* Operating Status: Beam is Off
*
* SECOND TARGET STATION
ORNL is moving forward with plans for a third neutron source: the Second
Target Station (STS) at SNS, to address emerging science challenges.
