European XFEL emitted its first beam in May 2017. It can now produce light with enough intensity to elucidate structures on nanometric or even atomic scales in a single pulse. Both the duration—on the order of a femtosecond—and the coherence of the light flashes will allow scientists to study the dynamics of biological structures, nano-objects, and chemical reactions in real time. In addition, the laser's exceptional brilliance will enable induction and observation of excited states of matter—such as those existing at the core of planets.

. Number of photons emitted per unit of time, per unit of angular divergence, per unit of cross-sectional area, for a given bandwidth.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
