Enlightening Science

The European XFEL is a research facility currently under construction in the Hamburg area, Germany. From 2017 on, it will generate extremely intense X-ray flashes to be used by researchers from all over the world.

The facility

The X-ray flashes will be produced in a 3.4-kilometre-long facility. Most of it will be housed in tunnels deep below ground. Three sites provide access to the tunnels and the experiment stations. (More)

Generation of X-ray flashes

Initially, a particle accelerator brings electrons to almost the speed of light. These electrons are then made to follow a tight slalom course on which they emit intense flashes of X-ray radiation. (More)


The European XFEL will open up completely new areas of experimentation. Its X-ray flashes will allow to map atomic details of viruses, film chemical reactions and study the processes in the interior of planets. (More)

The Company

The European XFEL is being constructed by the European XFEL GmbH. For the construction and operation, the company collaborates closely with DESY and many other institutions.
