Every year, about 2000 scientists from all over the world and from virtually all disciplines of natural science make their way to Hamburg to work at DESY photon sources. They take advantage of the unique light source FLASH, the world’s first free-electron laser generating radiation in the vacuum ultraviolet and soft X-ray regions, and PETRA III delivering X-ray radiation of an especially high brilliance. 20 beamlines with more than 60 instruments and experimental setups are available for user experiments at PETRA III and FLASH. The use of the facility is free of charge for academic research which is being published according to established standards. Special conditions and application procedures are offered for industrial users.

If you are interested in performing experiments at DESY Photon Science please first consult the webpages of PETRA III or FLASH
You may also contact the User Office.

Users from industry should contact the Service Group Industry first.

Briefly, you have to take the following steps on the way to beamtime and a successful experiment:

Step 1
For each experiment, users (except from industry) have to write a research proposal, ideally after consultation with the respective beamline scientist/ beamtime coordinator. Following the call for proposals, the project proposal has to be submitted via the DESY Online Office for Research with Photons DOOR. If you are a first time user, you will need to register to DOOR.

Step 2
As a next step, the proposal will be checked for general feasibility by an internal review, followed by the assessment by one of the international Project Review Panels (PRPs). According to their recommendation and ranking, DESY Photon Science will decide on approval. Beamtime will be distributed considering the recommendations of the PRPs and the requirements of the different user groups. Due to the high demand, beamtime cannot be guaranteed for all highly ranked projects.

Step 3
Especially users who prepare their first experiments at DESY photon sources should arrange their visit and prepare their experiments well in advance following the instruction given in the User Guide. In order to permit a smooth realization of your experiment and prevent any unnecessary loss of beamtime all technical questions should be discussed with the assigned local contact before your arrival at DESY.

DESY offers limited support for travel expenses for users from German universities and users from EU member countries and associated states. Applications for financial support have to be submitted in advance via DOOR, i.e. before your trip to Hamburg, but not prior to approval of your proposal and allocation of beamtime.

During and after the experiment
Details of what has to be done on-site during and after the experiment can be found in the User Guide.
