Invitations

Feedback about the outcome of the review and allocation process will be provided to all Main Proposers and Principal Investigators for all proposals submitted in a specific cycle as soon as possible, typically 14–15 weeks after the deadline of the call for proposals.

At the same time, more specific information will be provided to users in order to prepare for the experiment, in particular:

  • Information about submission of the A-form (in particular about registration of the experiment team, confirmation of the samples/substances used during the experiments, user funding in case of eligibility, and request for support for practical arrangements)
  • Details about the general online safety training, mandatory for all users
  • Information about the mandatory advance shipping notification concerning samples and other items needed for the experiment


A local contact familiar with the instrument setup will be assigned to coordinate support to the experiment.


The Main Proposer is responsible for collecting information, coordinating arrangements, and transmitting details about registration of the experiment team to European XFEL. The submission of an electronic A-form by the Main Proposer at least 4 weeks before the start of the measurements is mandatory for accessing the facility.

Only scientists registered through the A-form will be admitted to the experiment.
