Researchers carefully positioned lasers to compress billions of electrons together, creating a beam five times more powerful ...
What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...
Scientists have taken a giant leap forward in particle physics by creating an electron beam with five times more peak current ...
Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found ...
The researchers used the world’s largest and most powerful X-ray laser: the European X-Ray Free-Electron Laser (European XFEL) located in Schenefeld near Hamburg, Germany. This facility features ...
The most powerful ultrashort electron beam ever created offers new possibilities for recreating cosmic conditions in ...
The hard X-ray FEL has come of age. A free-electron laser is not like other lasers. It works by forcing a beam of electrons, travelling at nearly the speed of light, to oscillate in a long ...
