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 […]

A fresh look at restoring power to the grid

ALBUQUERQUE, N.M. — Climate change can alter extreme weather events, and these events have the potential to strain, disrupt or damage the nation’s grid. Sandia National Laboratories computer scientists have been working on an innovative computer model to help grid operators quickly restore power to the grid after a complete disruption, a process called “black […]

Sandia, AMD collaborate to improve stockpile mission

ALBUQUERQUE, N.M. — Sandia National Laboratories, in partnership with Los Alamos and Lawrence Livermore national labs, has awarded a contract to AMD that funds research and development of advanced memory technologies expected to accelerate high-performance simulation and computing applications in support of the nation’s stockpile stewardship mission. The National Nuclear Security Administration’s Advanced Simulation and […]

Sandia work at the heart of next generation nuclear reactor

LIVERMORE, Calif. — A team of Sandia National Laboratories researchers working on the reactor at the DIII-D National Fusion Facility is testing materials to make the next generation of fusion reactors, in the quest to develop more carbon-free energy sources. These magnetic confinement fusion reactors, called tokamaks, use magnetic fields to shape plasma into a […]

Economic impact: Sandia Labs tops $4.2B in spending for first time, added 480 jobs in FY22

ALBUQUERQUE, N.M. — For the first time, Sandia National Laboratories’ contributions to the economy have topped $4.2 billion in a fiscal year, supporting individuals, families and businesses at an unprecedented level. Total spending in fiscal year 2022, which ended Sept. 30, was $312 million more than the previous fiscal year. The spending includes labor, subcontracts, […]

National Hispanic technical honor goes to Sandia Labs engineer

ALBUQUERQUE, N.M. — Sandia National Laboratories data engineer Rudy Garcia received the 2022 Society of Hispanic Professional Engineers Technical Achievement and Recognition, or STAR, Award for his work in research and engineering of large software systems and remote-sensing applications, along with his expertise in cloud computing and big geospatial-data architectures. The Hispanic in Technology, Government, […]

DOE funds pandemic tracking software

LIVERMORE, Calif. — The Department of Energy has awarded $5 million to create tools to increase the nation’s level of preparedness for biological threats — including an infection rate tracking program for COVID-19 developed by a Sandia National Laboratories team in 2020. Jaideep Ray and Cosmin Safta developed an approach using publicly available data from states […]
