Galactic gamma-ray sources reveal birthplaces of high-energy particles

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Nine sources of extremely high-energy gamma rays comprise a new catalog compiled by researchers with the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All produce gamma rays with energies over 56 trillion electron volts (TeV) and three emit gamma rays extending to 100 TeV and beyond, making these the highest-energy sources ever observed in our galaxy. The catalog helps to explain where the particles originate and how they are accelerated to such extremes.

Colloidal quantum dot laser diodes are just around the corner

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Los Alamos scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as lasers. These novel, dual-function devices clear the path towards versatile, manufacturing-friendly laser diodes. The technology can potentially revolutionize numerous fields from photonics and optoelectronics to chemical sensing and medical diagnostics.

Michelle Thomsen, a Los Alamos National Laboratory fellow and guest scientist, was awarded the John Adam Fleming Medal by the American Geophysical Union today at a ceremony in San Francisco, Calif.

High-speed fire footage reveals key insights for power plant safety

DOE/Sandia National Laboratories

Fire protection and optical engineers at Sandia National Laboratories are using high-speed cameras and advanced algorithms, imaging and analytic methods to understand these high energy arcing faults between two conductors, such as the high-voltage bus bars in a switchgear at a power plant. Flames from experimental arc faults are filled with useful information that can help keep power plants operating safely.

Internships fuel research for engineering students from Puerto Rico

DOE/Sandia National Laboratories

The Consortium for Integrating Energy Systems in Engineering and Science Education, CIESESE, internship program, sponsored by the National Nuclear Security Administration, connects engineering students from five Hispanic-serving institutions with research at Sandia National Laboratories and the National Energy Technology Laboratory. The program has recently been extended through next summer.
