The European XFEL, located in the metropolitan Hamburg area, is a research facility of superlatives: The world's
largest X-ray free-electron laser generates ultrashort laser X-ray light flashes, 27 000 times per second and with
a brilliance that is a billion times higher than that of synchrotrons, the best sources for X-ray radiation before the
development of free-electron lasers. The facility features globally unique possibilities for research and industrial
scientists to pursue discoveries in the nanocosmos towards use in society.
