The DESY Photon Science 'Project Review Panels' (PRP) discuss and rate user proposals for new research projects at DESY light sources PETRA III and FLASH regarding their scientific excellence, their feasibility at the experimental station of choice, and their relevance to the general research programme.
Each PRP consists of approximately 3-10 external national and international experts (in total about 70 scientific referees, nominated for a period of 3 years) and a DESY Photon Science representative acting as secretary. New referees are nominated by the present members and the DESY Photon Science Management. An additional Project Evaluation Committee (PEC) organized by EMBL evaluates proposals submitted for biocrystallography experiments at P11 and the EMBL Life Science beamlines P12-P14.
The PRP meetings are scheduled twice a year (April/May and October/November). During the meetings the reviewers agree on the final ratings for each proposal. According to the reviewers’ recommendation and ranking, the DESY Photon Science management decides on the approval. The beamtime is distributed considering the ranking given by the PRPs and the total number of beamtime shifts available at the respective beamline.
Due to the high demand, experimental stations at DESY Photon Science are generally overbooked, and beamtime cannot be guaranteed for all highly ranked projects. After finalization of the beamtime schedule of each beamline DESY Photon Science informs the users about the acceptance of their proposals and the beamtime allocated. The beamtime schedules for each beamline at PETRA III and FLASH are published on the DESY Photon Science web pages.
The use of the facilities is free of charge for academic research, as long as the results are being published according to established standards.
The PRPs cover the following reseach fields:
- VUV- and Soft X-ray
- X-ray Spectroscopy
- High Pressure and Extreme Conditions
- Engineering Materials Science
- Soft Condensed Matter: Bulk
- Soft Condensed Matter: Surfaces and Interfaces
- Imaging (full-field, scanning, coherent)
- Methods and Instrumentation
- Hard Condensed Matter: Surface and Coherent Scattering
- Hard Condensed Matter: Bulk (diffraction and scattering)
- Soft X-ray - FEL Experiments (FLASH)
- PEC: EMBL Life Science beamlines P12-P14 and biocrystallography at P11
