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 […]

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 […]

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 […]

Tritium introduced in fusion experiments at Sandia

More powerful fuel to boost Z Machine’s neutron output ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories Z Machine have opened a new chapter in their 20-year journey toward higher fusion outputs by introducing tritium, the most neutron-laden isotope of hydrogen, to their targets’ fuel. When Z fires, its huge electromagnetic field crushes pre-warmed fuel, […]

Sandia researcher wins high-voltage award

ALBUQUERQUE, N.M. — Awards arrive at different levels of intensity, but no one can deny that Sandia National Laboratories researcher Mark Savage has won the highest voltage prize of all — the IEEE William G. Dunbar Award — for work achieved at extremely high voltage. Asked why he was selected for the honor, Savage quipped, […]

Sandia physicist Jim Bailey wins major physics award for 10-year study of the sun

ALBUQUERQUE, N.M. — By testing bits of iron at the temperature of the sun, Sandia National Laboratories physicist Jim Bailey and his team have provided key data to improve the Standard Solar Model, widely used by astrophysicists to help model the behavior of stars. For this work, Bailey will receive the American Physical Society’s annual […]

World’s fastest multiframe digital X-ray camera created at Sandia

ALBUQUERQUE, N.M. — An adversary who steps inside a boxer’s sense of rhythm may land a punch the boxer never saw coming. A similar problem faces physicists struggling to achieve laboratory-scale nuclear fusion: A rogue event occurring between successively monitored images may knock an otherwise promising experiment off-kilter without anyone seeing the cause. To narrow […]

Thor’s hammer to crush materials at 1 million atmospheres

Sophisticated features may influence eventual Z-machine rebuild ALBUQUERQUE, N.M. — A new Sandia National Laboratories accelerator called Thor is expected to be 40 times more efficient than Sandia’s Z machine, the world’s largest and most powerful pulsed-power accelerator, in generating pressures to study materials under extreme conditions. “Thor’s magnetic field will reach about one million […]

Sandia researcher elected physics fellow after ‘remarkable impact’ in pulsed power

ALBUQUERQUE, N.M. — Sandia National Laboratories researcher Daniel Sinars has been elected a fellow of the American Physical Society (APS) through its Division of Plasma Physics. The distinction is awarded to no more than one half of one percent of the society’s membership. Sinars’ citation reads, “For scientific contributions and leadership in the development of […]

Sandia’s Z machine receives funding aimed at fusion energy

Laser beam ‘smoothing’ with University of Rochester to play key role ALBUQUERQUE, N.M. — A two-year, $3.8 million award has been received by Sandia National Laboratories and the University of Rochester’s Laboratory for Laser Energetics (LLE) to hasten the day of low-cost, high-yield fusion reactions for energy purposes. High-yield means much more energy emerging from […]

Pulsed-power physicist receives IEEE Nuclear and Plasma Science award

ALBUQUERQUE, N.M. — William Stygar, manager of Sandia National Laboratories’ Advanced Accelerator Physics department, has been selected to receive the Erwin Marx Award by the Pulsed Power Science and Technology Committee of the IEEE Nuclear and Plasma Science Society. The award’s previous recipients “are a who’s who of the leaders in pulsed power science and […]

Sandia magnetized fusion technique produces significant results

ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories’ Z machine have produced a significant output of fusion neutrons, using a method fully functioning for only little more than a year. The experimental work is described in a paper to be published in the Sept. 24 Physical Review Letters online. A theoretical PRL paper to be […]

American Physical Society names four Sandia fellows

ALBUQUERQUE, N.M. — Four Sandia researchers have been named Fellows of the American Physical Society, an honor that indicates recognition by scientific peers of exceptional contributions to physics. No more than one half of 1 percent of APS membership can be elected in a given year. Those honored are: Charles Barbour, for outstanding contributions to […]

Japanese city councilor journeys to end furor over Sandia Z tests

ALBUQUERQUE, N.M. — Yasuyuki Kaneko left his wife and two small children at the end of April to fly from the northern Japanese city of Sapporo to Albuquerque. He stayed overnight at a small hotel a few blocks from the airport. The next morning, Kaneko — a Sapporo city councilor — took the final step of […]
