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.

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.
