Science Area: Neutron Science

ORNL Image

Although the neutron is a senior citizen of sorts, whose existence was predicted in 1920 and confirmed in 1932, it’s still not fully understood.

It was James Chadwick of Cambridge’s Cavendish Laboratory who, after nearly a decade of experimentation, devised a method to detect these particles, whi...

The world below our feet can be as important as the one we see around us. It provides many things we need, including drinking water, but it also carries contaminants that poison that water.

Much of what we know about underground contamination comes from scientists such as geochemist David Wesolow...

It produces more than 2 million billion neutrons each second through an area less than half the size of a dime, providing researchers with the Western world’s highest reactor-based neutron flux. Its neutron scattering stations allow scientists to better understand the structure and dynamics of matte...

Paul Langan is the associate laboratory director for neutron sciences at Oak Ridge National Laboratory. He came to ORNL in April 2011 as a senior scientist and director of the Center for Structural Molecular Biology. In October of that year he became founding director of the Neutron Sciences Directo...

Neutrons are a precious scientific resource—electrically neutral, strongly penetrating, and energetically well matched to elementary excitations in matter. They see atoms and ions and differences in isotopic composition. They follow motions. And they reveal magnetic and electronic properties that ar...

At 2:22 PM on August 25, 1965, the High Flux Isotope Reactor achieved criticality for the first time. Just over a year later, HFIR reached its design power of 100 megawatts, delivering the highest neutron flux of any research reactor in the world.

As its name implies, HFIR’s primary ...
