SwissFEL Proposals

Scientists are invited to submit proposals asking for a specified amount of the user time. A call for proposals is published by email and on the SwissFEL web site. There are two calls for proposals per year.
Proposals have to be submitted using the SwissFEL Digital Users Office (DUO).
Information/Notification on open calls is found at: The proposals are submitted to and handled by the PSI Digital User Office (DUO). The proposals will be selected by an independent international peer review committee on the basis of scientific criteria. The scheduling periods and deadlines for calls for proposals can be found in detail at SwissFEL Proposal Calls.

Please note: Successful applicants will be allowed access free of charge, including logistic, technical, and scientific support.
Please read and respect our guidelines for good scientific practice: Scientific Integrity Guidance

This includes that authorship must be discussed and agreed upon at an early stage with all those involved (p. 28 of the guideline). We encourage you to clarify with your local contact prior to your beamtime whether you ask for user support or would like to conduct your project in collaboration with beamline staff.
