+    Join us for an exciting opportunity to explore the European XFEL! The 3.4 kilometers (2.11 miles) long European XFEL generates extremely intense X-ray flashes used by researchers from all over the world. The X-ray flashes are produced in underground tunnels and allow scientists to map atomic details of viruses, film chemical reactions, and study processes like those in the interior of planets. On this tour, we will also visit the newly opened visitor center featuring an engaging exhibition. Moreover, we will descend five floors underground to the experimental hall, where researchers utilize X-ray beams for their experiments.
