The Department of Energy’s Office of Nuclear Energy has selected Lou Qualls as the national technical director for molten salt reactors (MSRs). In his new role, Qualls—a nuclear engineer who joined DOE’s Oak Ridge National Laboratory in 1988—will serve as a liaison among the nuclear industry, the national laboratory system and DOE in defining the future of MSR technology in the United States.
Placing a magnet on your refrigerator might hold up your calendar, but researchers from India’s Saha Institute of Nuclear Physics found that placing one outside a plasma chamber causes a localized, fireball-like structure. This work may help understand plasma dynamics under these north-south, or dipolar, magnetic fields. They present their results this week in the journal Physics of Plasmas, from AIP Publishing.
In a unique groundbreaking ceremony July 21 at the Sanford Underground Research Facility in Lead, S.D., an international group of dignitaries, scientists and engineers will mark the start of construction of a massive experiment that could change our understanding of the universe.
A Berkeley Lab-led report highlights a new, compact technique for producing beams with precisely controlled energy and direction that could “see” through thick steel and concrete to more easily detect and identify concealed or smuggled nuclear materials for national security and other applications.
The University of Utah’s J. Marriott Library created an interactive, geospatial archive depicting the story of Utah radioactive fallout related to atmospheric nuclear testing at the Nevada Test Site.
A team of Notre Dame researchers are working in collaboration with researchers from the South Dakota School of Mines and Technology and the Colorado School of Mines.
Like water, neutrons seek their own level, and watching how they flow may teach us about how the chemical elements were made.
FIONA (For the Identification Of Nuclide A) is a newly installed device designed to measure the mass numbers of individual atoms of heavy and superheavy elements. FIONA will let researchers learn about the shape and structure of heavy nuclei, guide the search for new elements, and offer better measurements for nuclear fission and related processes.
Raul Briceno was presented with the 2017 Kenneth G. Wilson Award for Excellence in Lattice Field Theory on June 22. The award citation noted his “groundbreaking contributions to the study of resonances using lattice QCD."
It’s not unusual for anyone to shop online at Amazon, but one young scientist went to the website looking for more than a favorite book. University of Connecticut Postdoctoral Researcher Nobuo Sato plans to conduct theoretical research in nuclear physics using the online retailer’s computing services, and he has been awarded the 2017 JSA Postdoctoral Research Grant to do it.
Article describes first experimental finding of constant temperature throughout a fusion plasma.
A new technique allows researchers to characterize nuclear material that was in a location even after the nuclear material has been removed – a finding that has significant implications for nuclear nonproliferation and security applications.
Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders.
The Relativistic Heavy Ion Collider (RHIC) and ATLAS Computing Facility (RACF) Mass Storage Service—part of the Scientific Data and Computing Center (SDCC) at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—now records 100 petabytes of data reflecting nearly two decades of physics research.
It’s been a challenge for Sandia National Laboratories' Tonopah Test Range to keep decades-old equipment running while gathering detailed information required for 21st century non-nuclear testing. The Nevada test range has changed the analog brains in instruments to digital, moved to modern communications systems, and upgraded telemetry and tracking equipment and computing systems.
Food in Japan will be contaminated by low-level radioactivity for decades following the 2011 Fukushima nuclear disaster, but not at a level which poses a serious risk to human health, according to new research.
Northwestern’s astrophysics center, CIERA (the Center for Interdisciplinary Research and Exploration in Astrophysics), is leading a new crowdsourcing project called Gravity Spy to sift through the massive amounts of data being produced by the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors located in the U.S.
When scientists at the Department of Energy’s SLAC National Accelerator Laboratory focused the full intensity of the world’s most powerful X-ray laser on a small molecule, they got a surprise: A single laser pulse stripped all but a few electrons out of the molecule’s biggest atom from the inside out, leaving a void that started pulling in electrons from the rest of the molecule, like a black hole gobbling a spiraling disk of matter.
Jefferson Science Associates, LLC, announced today that Charles Perdrisat and Charles Sinclair are the recipients of the 2017 Outstanding Nuclear Physicist Prize. The 2017 JSA Outstanding Nuclear Physicist Award is jointly awarded to Charles Perdrisat for his pioneering implementation of the polarization transfer technique to determine proton elastic form factors, and to Charles Sinclair for his crucial development of polarized electron beam technology, which made such measurements, and many others, possible.
Neutrons are inherently unstable and don’t last long outside an atomic nucleus, and because they decay on a time scale similar to the period for Big Bang Nucleosynthesis, accurate simulations of the BBN era require thorough knowledge of the neutron lifetime, but this value is still not precisely known. This week in Review of Scientific Instruments, scientists at Los Alamos National Lab report an exciting new method to measure it.
