Neutron production at ORNL's SNS reaches design power level

DOE/Oak Ridge National Laboratory

The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle at its design power level of 1.4 megawatts.

Leah Broussard: Breaking the standard model to fix understanding of the universe

DOE/Oak Ridge National Laboratory

Leah Broussard, a physicist at the Department of Energy's Oak Ridge National Laboratory, has so much fun exploring the neutron that she alternates between calling it her 'laboratory' and 'playground' for understanding the universe. Neutrons can help identify where the Standard Model 'breaks.' Some of Broussard's experiments amount to 'crash tests' that push physics to its limits to see what in the model is missing or wrong.

Seven ORNL researchers named 2019 INCITE award winners

DOE/Oak Ridge National Laboratory
Grant and Award Announcement

Seven researchers from the Department of Energy's Oak Ridge National Laboratory have been chosen by the Innovative and Novel Computational Impact on Theory and Experiment, also known as INCITE, program to lead scientific investigations that require the nation's most powerful computers. The ORNL-based projects span a broad range of the scientific spectrum and represent the potential of high-performance computing in ensuring America's scientific competitiveness and energy security.

Self-sensing materials are here

DOE/Oak Ridge National Laboratory

Researchers at the Department of Energy's Oak Ridge National Laboratory invented a roll-to-roll process to coat electrically conductive carbon fibers with semiconducting silicon carbide nanoparticles. This nanomaterial-embedded composite is stronger than other fiber-reinforced composites and imbued with a new capability--the ability to monitor its own structural health.

Big jobs: Safety, planning key to increasing production performance at SNS

DOE/Oak Ridge National Laboratory

In December 2017, the Spallation Neutron Source at Oak Ridge National Laboratory entered into an extended 5-month scheduled outage to perform a number of high-priority jobs. Most notable were the replacement of the facility's inner reflector plug and the accelerator's radio frequency quadrupole. The success of the long outage demonstrated the ability to plan and execute future upgrade and construction projects such as the Proton Power Upgrade and the Second Target Station.

Scientists find great diversity, novel molecules in microbiome of tree roots

DOE/Oak Ridge National Laboratory

Researchers with the Department of Energy's Oak Ridge National Laboratory have discovered that communities of microbes living in and around poplar tree roots are ten times more diverse than the human microbiome and produce a cornucopia of novel molecules that could be useful as antibiotics, anti-cancer drugs, or for agricultural applications.

Feeling the need for speed, neutrons study fluid flow for hypersonic flight

DOE/Oak Ridge National Laboratory

Searching for solutions to supersonic fluid flow behavior, researchers from the University of Tennessee, Knoxville, and the U.S. Air Force are using neutron radiography at DOE's ORNL. The team says a better understanding of spray dynamics will lead to improved fuel injector designs for the aeronautic and automotive industries as well as other spray-related applications used in agriculture, pharmaceuticals, manufacturing, and more.
