Precise atom implants in silicon provide a first step toward practical quantum computers

ALBUQUERQUE, N.M. — Sandia National Laboratories has taken a first step toward creating a practical quantum computer, able to handle huge numbers of computations instantaneously. Here’s the recipe: A “donor” atom propelled by an ion beam is inserted very precisely in microseconds  into an industry-standard silicon substrate. The donor atom — in this case, antimony […]

Ingenious method enables sharper flat-panel displays at lower energy costs

ALBUQUERQUE, N.M. — A perpetual quest of  manufacturers and viewers is for ever-brighter colors and better images for flat-panel displays built from less expensive materials that also use less electricity. An intriguing method discovered by Sandia National Laboratories researcher Alec Talin and collaborators at the Center for Nanoscale Science and Technology at the National Institute […]

Unique phononic filter could revolutionize signal processing systems

ALBUQUERQUE, N.M. — A unique filtering technology that combines light and sound waves on a single chip is expected to better detect radar and communications frequencies. “We have developed a powerful signal filtering technology that could revolutionize signal processing systems that rely solely on conventional electronics,” said Patrick Chu, manager of applied photonic microsystems for […]

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 physicist accepts first joint faculty appointment with Washington State University

ALBUQUERQUE, N.M. — Sandia National Laboratories physicist Marcus Knudson is the first joint faculty appointee to serve both Sandia and Washington State University (WSU). In the position, Knudson will enhance fundamental research into the compression of materials under extreme conditions, using Sandia’s unique Z machine. “The science of dynamic material compression is a core capability […]

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 […]

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 […]

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 […]

‘Iron Sun’ is not a rock band, but a key to how stars transmit energy

ALBUQUERQUE, N.M — Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band — the section of […]
