Free-electron laser (FEL) sources can generate tunable short-wavelength coherent pulses that can be used for studying structure and dynamics of matter in different forms. In this open collection, we ...
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 ...
