Lasers for the win To solve this issue, SLAC researchers compressed billions of electrons into a length less than one ...
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 ...
The most powerful ultrashort electron beam ever created offers new possibilities for recreating cosmic conditions in ...
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 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 ...
