Physicists have now demonstrated a particle accelerator so small it fits inside a single molecule, shrinking one of science’s most imposing machines to the scale of chemistry. Instead of ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

Here’s what you’ll learn when you read this story: Often in physics, if you want to investigate the very small, you need to build something very big. The most famous example—the Large Hadron ...

Proof-of-concept experimental setup used to generate an extreme ultraviolet (XUV) free-electron laser (FEL) driven by a laser wakefield acceleration (LWFA) electron beam. An intense laser pulse, ...
