91°µÍø

The COHERENT particle physics experiment at the Department of Energy’s 91°µÍø has firmly established the existence of a new kind of neutrino interaction.

Since the 1930s, scientists have been using particle accelerators to gain insights into the structure of matter and the laws of physics that govern our world.

Marcel Demarteau is director of the Physics Division at the Department of Energy’s 91°µÍø. For topics from nuclear structure to astrophysics, he shapes ORNL’s physics research agenda.

Six scientists at the Department of Energy’s 91°µÍø were named Battelle Distinguished Inventors, in recognition of obtaining 14 or more patents during their careers at the lab.

A new study clears up a discrepancy regarding the biggest contributor of unwanted background signals in specialized detectors of neutrinos.

ORNL has added 10 virtual tours to its campus map, each with multiple views to show floor plans, rotating dollhouse views and 360-degree navigation. As a user travels through a map, pop-out informational windows deliver facts, videos, graphics and links to other related content.

Geoffrey L. Greene, a professor at the University of Tennessee, Knoxville, who holds a joint appointment with ORNL, will be awarded the 2021 Tom Bonner Prize for Nuclear Physics from the American Physical Society.

For over half a century, Robert Compton has been a celebrated experimentalist and inspirational leader and teacher in the fields of physics and chemistry. Compton came to work at ORNL's Health Sciences Research Division in 1965 after receiving his doctorate in physics from the University of Tennessee.

Rufus Ritchie came from Kentucky coal country, a region not known for producing physicists.

Herb Mook was a driving force in ORNL neutron s​cience ​for four decades, a prolific and pioneering experimentalist, and a leader and mentor for generations of neutron scattering scientists.
