Benchmarking the Continuous Electron Beam Accelerator Facility

It’s a paper that’s been more than four decades in the making. Published in Physical Review Accelerators and Beams, a study has re-benchmarked the main particle accelerator at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility. It has captured the accelerator’s original and upgraded operating parameters and describes in detail its main systems […]

Scientists pioneer novel heat-to-electricity conversion in semimetal WSi₂

Thermoelectric materials, which convert heat into electricity, are valuable tools for capturing waste heat and turning it into usable electricity. These materials are especially useful in industries and vehicles where engines produce a lot of waste heat, improving energy efficiency by converting it into additional power. They also exhibit potential for portable power generation, in […]

Simple method can recover and recycle quantum dots in microscopic lasers

Researchers have discovered a way to recycle the tiny particles used to create supraparticle lasers, a technology that precisely controls light at a very small scale. The breakthrough could help manage these valuable materials in a more sustainable way.

Twisted light gives electrons a spinning kick: Researchers develop a novel way to control quantum interactions

It’s hard to tell when you’re catching some rays at the beach, but light packs a punch. Not only does a beam of light carry energy, it can also carry momentum. This includes linear momentum, which is what makes a speeding train hard to stop, and orbital angular momentum, which is what the Earth carries […]
