The European XFEL is a research facility open to scientists worldwide. Beamtime is free of charge, but experiment proposals must go through a peer-review process. Proposals must be submitted through the User Portal to the European XFEL (UPEX) in the frame of specific calls for proposals. As an important condition for access, after the experiments, the authors must strive to publish the results in peer-reviewed journals.
