Super-Earth atmospheres probed at Sandia’s Z machine

ALBUQUERQUE, N.M. — The huge forces generated by the Z machine at Sandia National Laboratories are being used to replicate the gravitational pressures on so-called “super-Earths” to determine which might maintain atmospheres that could support life. Astronomers believe that super-Earths — collections of rocks up to eight times larger than Earth — exist in the […]

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 […]

New device in Z machine measures power for nuclear fusion

ALBUQUERQUE, N.M. — If you’re chasing the elusive goal of nuclear fusion and think you need a bigger reactor to do the job, you first might want to know precisely how much input energy emerging from the wall plug is making it to the heart of your machine. If somewhere during that journey you could […]

Black hole models contradicted by hands-on tests at Sandia’s Z machine

ALBUQUERQUE, N.M. — A long-standing but unproven assumption about the X-ray spectra of black holes in space has been contradicted by hands-on experiments performed at Sandia National Laboratories’ Z machine. Z, the most energetic laboratory X-ray source on Earth, can duplicate the X-rays surrounding black holes that otherwise can be watched only from a great distance and then theorized […]

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 […]

Sandia’s Z machine helps solve Saturn’s 2-billion-year age gap

Research supports 80-year-old prediction ALBUQUERQUE, N.M. — Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a two-billion-year discrepancy for computer models estimating Saturn’s age. “Models that correctly predict Jupiter to be 4.5 billion years old […]

Iron rain fell on early Earth, new Z machine data supports

ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories’ Z machine have helped untangle a long-standing mystery of astrophysics: why iron is found spattered throughout Earth’s mantle, the roughly 2,000-mile thick region between Earth’s core and its crust. At first blush, it seemed more reasonable that iron arriving from collisions between Earth and  planetesimals — ranging […]

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 […]

Second Z plutonium “shot” safely tests materials for NNSA

ALBUQUERQUE, N.M. — The National Nuclear Security Administration (NNSA) today announced that researchers from Sandia and Los Alamos national laboratories have completed their second experiment in the past six months at Sandia’s Z machine to explore the properties of plutonium materials under extreme pressures and temperatures. The information is used to keep the U.S. nuclear […]

Exploring explosives for expanding geothermal energy

ALBUQUERQUE, N.M. — Why are scientists setting off small-scale explosions inside 1-foot cubes of plexiglass? They’re watching how fractures form and grow in a rock-like substance to see if explosives or propellants, similar to jet fuel, can connect geothermal wells in a predictable manner. Geothermal energy has a lot of promise as a renewable energy […]

Sandia weapons systems engineering director honored by NNSA, Air Force and Navy

ALBUQUERQUE, N.M. — Jim Handrock, Sandia National Laboratories’ director of New Mexico weapons systems engineering, received a series of awards and commendations from the National Nuclear Security Administration, the Air Force and Navy recognizing his leadership, expertise and service to the nation during a celebration at Sandia on May 4. The celebration, held on Kirtland […]

Build-a-satellite program could fast track national security space missions

ALBUQUERQUE, N.M. — Satellites equipped with remote sensing technology execute many critical national security missions, from detecting explosions to tracking sea ice, but until now it could take a team years to move from a concept to a deployable space system. Valhalla, a Python-based performance modeling framework developed at Sandia National Laboratories, uses high-performance computing […]

Sandia researcher Ray Tuminaro named SIAM fellow

ALBUQUERQUE, N.M. — Sandia computational scientist and applied mathematician Ray Tuminaro has been named a 2022 Fellow of the Society for Industrial and Applied Mathematics for “contributions in iterative linear-solver algorithms and software that address scientific computing applications on large-scale parallel systems.” A distinguished member of Sandia’s technical staff, Tuminaro has been praised for exceptional […]

National group honors Sandia Labs recruiter as veterans champion

ALBUQUERQUE, N.M. — Sandia National Laboratories talent acquisition specialist Tony Lona, a recruiter focused on veterans and unique abilities, was named a 2022 Veteran Champion of the Year in Corporate America by G.I. Jobs Magazine. The award is presented to those who champion the recruitment, hiring, retention and career advancement of U.S. military veterans in […]

Together we rise

ALBUQUERQUE, N.M. — As fierce wildfires spread through New Mexico, burning hundreds of structures and forcing thousands of residents to evacuate, Sandia National Laboratories found a way for the workforce to help. “We know that when people in our state are struggling, our staff feel the desire and immediate need to react and pull together,” […]
