Remote high-voltage sensor unveiled at Sandia gamma ray lab

November 10, 2021 • 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,...
Sandia National Laboratories researcher Israel Owens holds the optical sensor used to house the crystal that proved central to his team’s successful attempts to measure very high voltages. The two red spots on each side of the crystal are due to laser light reflecting off the side mirrors used to direct light through the middle of the crystal. The actual experiments used green laser light.

Radiation-detecting plastic gets ingredient to stay in the clear

April 30, 2020 • LIVERMORE, Calif. — Researchers at Sandia National Laboratories have identified a straightforward change to the formula for radiation-detecting plastic. The change prevents “fogging,” which reduces the lifetime of the plastics used to detect nuclear material transiting through the U.S. Department of Homeland Security’s radiation detectors. The change also fits well...

Quantum computing steps further ahead with new projects at Sandia

January 7, 2019 • ALBUQUERQUE, N.M. — Quantum computing is a term that periodically flashes across the media sky like heat lightning in the desert: brilliant, attention-getting and then vanishing from the public’s mind with no apparent aftereffects. Yet a multimillion dollar international effort to build quantum computers is hardly going away. And now,...

Sandia microneedles technique may mean quicker diagnoses of major illnesses

January 2, 2019 • ALBUQUERQUE, N.M. — When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw — usually performed by a medical professional armed with an uncomfortably large needle — might not be quickest, least painful or...
