Program in fusion energy attracted interns’ eyes

 ALBUQUERQUE, N.M.— A bold plan paid off this past summer when Sandia National Laboratories staff members LaRico Treadwell and Khalid Hattar combined their passions for increasing inclusion of people of color with developing materials to eventually derive energy from nuclear fusion. Standing to benefit from the pilot project were three undergraduate interns from North Carolina […]

Remote high-voltage sensor unveiled at Sandia gamma ray lab

ALBUQUERQUE, N.M. — Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages. Now, using a crystal smaller than a dime and a laser smaller than a shoebox, a Sandia National Laboratories team […]

Vacuum Package

This device could usher in GPS-free navigation

ALBUQUERQUE, N.M. — Don’t let the titanium metal walls or the sapphire windows fool you. It’s what’s on the inside of this small, curious device that could someday kick off a new era of navigation. For over a year, the avocado-sized vacuum chamber has contained a cloud of atoms at the right conditions for precise […]

Sandia researcher awarded Early-Career Research Program grant

ALBUQUERQUE, N.M. — Working to solve a problem, supercomputing researchers may encounter incomplete data or flawed programs. For both issues, Sandia researcher Drew Kouri has attracted interest from the broad computing community for his ability to mitigate uncertainty in both supercomputer programs and data, optimizing each to reach the best solutions. His research was awarded […]

Look who’s turning 25

ALBUQUERQUE, N.M. — Sandia National Laboratories is celebrating 25 years of research conducted at its Z Pulsed Power Facility — a gymnasium-sized accelerator commonly referred to as Z or the Z machine. Due to COVID-19 restrictions, only a limited number of former leaders of the pulsed power program at Sandia will gather Friday to share […]

World’s smallest, best acoustic amplifier emerges from 50-year-old hypothesis

ALBUQUERQUE, N.M. — Scientists at Sandia National Laboratories have built the world’s smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost 50 years. According to a paper published May 13 in Nature Communications, the device is more than 10 times more effective than the earlier […]

Rare open-access quantum computer now operational

ALBUQUERQUE, N.M. — A new Department of Energy open-access quantum computing testbed is ready for the public. Scientists from Indiana University recently became the first team to begin using Sandia National Laboratories’ Quantum Scientific Computing Open User Testbed, or QSCOUT. Quantum computers are poised to become major technological drivers over the coming decades. But to […]

Sandia nuclear physicist selected fellow of AAAS

ALBUQUERQUE, N.M. — Susan Seestrom, associate laboratories director for advanced science and technology and chief research officer at Sandia National Laboratories, has been named a fellow of the American Association for the Advancement of Science. The physicist was cited “for her pathbreaking work in nuclear physics, especially using ultra cold neutrons, and her leadership, both […]

Record neutron numbers at Sandia Labs’ Z machine fusion experiments

ALBUQUERQUE, N.M.— A relatively new method to control nuclear fusion that combines a massive jolt of electricity with strong magnetic fields and a powerful laser beam has achieved its own record output of neutrons — a key standard by which fusion efforts are judged — at Sandia National Laboratories’ Z pulsed power facility, the most […]

Machine-learning technique from Sandia Labs could improve fusion energy outputs

ALBUQUERQUE, N.M. — Machine-learning techniques, best known for teaching self-driving cars to stop at red lights, may soon help researchers around the world improve their control over the most complicated reaction known to science: nuclear fusion. Fusion reactions are typically hydrogen atoms heated to form a gaseous cloud called a plasma that releases energy as […]

50 million artificial neurons to facilitate machine-learning research at Sandia

ALBUQUERQUE, N.M. — Fifty million artificial neurons — a number roughly equivalent to the brain of a small mammal — were delivered from Portland, Oregon-based Intel Corp. to Sandia National Laboratories last month, said Sandia project leader Craig Vineyard. The neurons will be assembled to advance a relatively new kind of computing, called neuromorphic, based […]

Basic laws of physics spruce up machine learning

ALBUQUERQUE, N.M. — A proposed project to help scientists use the laws of physics to view multiscale physical events with a clarity never before achieved has won an Early Career Research Program award from the Department of Energy for Sandia National Laboratories researcher Nathaniel Trask. Such work may require observations over a millionfold change in […]

Sandia to receive Fujitsu ‘green’ processor

ALBUQUERQUE, N.M. — This spring, Sandia National Laboratories anticipates being one of the first Department of Energy laboratories to receive the newest A64FX Fujitsu processor, a Japanese Arm-based processor optimized for high-performance computing. Arm-based processors are used widely in small electronic devices like cell phones. More recently, Arm-based processors were installed in Sandia’s Astra supercomputer, […]

Sandia initiatives to protect US energy grid and nuclear weapons systems

ALBUQUERQUE, N.M. — To deter attempts to disable U.S. electrical utilities and to defend U.S. nuclear weapon systems from evolving technological threats, Sandia National Laboratories has begun two multiyear initiatives to strengthen U.S. responses. One is focused on defending large U.S. electrical utility systems from potential attacks by hostile nations, as well as from damage […]

Sandia Fellow wins nuclear fusion award

ALBUQUERQUE, N.M. — Sandia National Laboratories Fellow Keith Matzen has been awarded the 2019 Distinguished Career Award by Fusion Power Associates, a national nonprofit research and educational foundation, for his many contributions to the laboratory development of nuclear fusion. The foundation annually brings together senior U.S. and international fusion experts to review the status of […]
