Free-electron lasers providing ultra-short high-brightness pulses of X-ray radiation have great potential for a wide impact on science, and are a critical element for unravelling the structural ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

Scientists have demonstrated a new method for generating and sustaining the high-quality electron beams required for X-ray lasers, a step toward making the instruments smaller and more affordable. The ...
