Calls for Proposals

The European X-Ray Free-Electron Laser Facility (European XFEL) is expecting to see first X-ray FEL light in the first half of 2017 and plans to start the Early User Experiment programme shortly thereafter.

European XFEL encourages the scientific community worldwide to propose experiments for Early User Experiments on the two scientific instruments scheduled to start their early user programme in the second half of 2017: the Femtosecond X-Ray Experiments (FXE) and the Single Particles, Clusters and Biomolecules / Serial Femtosecond Crystallography (SPB/SFX) instruments.
The planned first allocation period includes about 800 hour beamtime in total (about 400 hours per Instrument) between September and November 2017. Precise dates will be confirmed depending on the commissioning progress currently under way. The allocated beamtime will be measured in 12-hour shifts.

Outcome of beamtime allocation process: end of June 2017

All proposals submitted in the first call will be reviewed for their scientific quality by panels of international experts (Proposal Review Panels) and also checked about safety and feasibility conditions. More information about the composition and the organization of the Proposal Review Panels can be found here:

http://www.xfel.eu/organization/company/proposal_review_panels

For early operation conditions, please refer to the relevant Instrument homepages:

Given that the European XFEL is a brand-new facility, the conditions above will be subject to periodic improvement, as needed.

All Proposals must be submitted through the User Portal to the European XFEL (UPEX)

You will find more information on the available infrastructure, specific contacts and instructions in the following documentation.
Travel funding will be made available to part of the participants in experiments allocated beamtime if their affiliation is based in one of the countries supporting the European XFEL. Further information on travel rules will be available soon.
