Review and Approval

Project Review Panels

Depending on the facility requested and the scientific topic, project proposals are reviewed by one of nine international Research Project Review Panels (PRPs) considering:

  • scientific excellence of the proposal
  • the fundamental feasibility at DESY Photon Science
  • the suitability for the proposed instrument
  • in case users have already performed experiments at DESY Photon sources: publication record related to this earlier work

Proposals that do not meet the proposal guidelines with respect to length and content may be excluded from the review process by the PRPs.

The final approval of proposals is issued by the DESY Photon Science Management in agreement with the PRPs and under consideration of available beamtime. The DESY Photon Science Management notifies the applicant about the results of the research proposal evaluation and whether beamtime has been allocated - usually 3-4 weeks after the last PRP meeting(s) by mail. Please note that due to overbooking of the facilities even highly ranked proposals may not receive beamtime.

For FLASH proposals the additional step of beamtime application via DOOR is necessary after approval of the project.

The user will also be assigned a local contact who should be contacted soon after the notification.

The Photon Science Management reserves the right to accept promising and outstanding test experiments on short notice.
In addition, the management also reserves the right to reject proposals that are not in accordance with the users' obligation to pursue exclusively research for peaceful purposes during any experiments carried out at DESY.
