Hamburg supports DESY´s large-scale project PETRA IV

The world´s best 3D X-ray microscope is to be located in Bahrenfeld in the future


Hamburg is supporting the technology development for DESY´s planned large-scale project PETRA IV with 2.85 million euros over the next two years. Funding is being provided for the detailed technical planning phase, the so-called Technical Design Report (TDR) of the unique facility, as a precondition for a decision on the inclusion of the project in the national roadmap for research infrastructures. PETRA IV is set to become the world´s best 3D X-ray microscope, providing images of microscopic processes in new materials and in future medical agents that are hundreds of times more accurate than previously possible. PETRA IV will thus become the scientific beacon project in the future Science City Hamburg Bahrenfeld.

Hamburg´s science senator Katharina Fegebank: “Hamburg can be pleased and proud: PETRA IV will offer unique research opportunities worldwide and has the potential to become the scientific flagship of Science City Hamburg Bahrenfeld. The Senate therefore supports the development of the state-of-the-art technologies for the accelerator facility and thus ensures that Hamburg can continue to develop into a world-class science and research metropolis.”

Helmut Dosch, Chairman of the DESY Board of Directors, says: “With PETRA IV, DESY is creating a completely new tool in basic research and for innovations in the fields of new materials, health, environment and sustainable energy concepts. The funding for the important TDR phase helps us to develop the new technologies that are indispensable for this and thus to create a robust design for this revolutionary large-scale project.”

With a federal share of 90 per cent, further important financial support is available to DESY from the institutional funding provided by the Federal Ministry of Education and Research (BMBF) which is supplemented by a state share of ten per cent.


The Helmholtz Research Centre DESY, with sites in Hamburg and Zeuthen in Brandenburg, receives 90 per cent of its funding from the Federal Government (BMBF) and ten per cent from the Senate at its Hamburg site.

DESY is currently planning to improve its brilliant electron storage ring PETRA III even further and to expand it into the ultimate 3D X-ray microscope PETRA IV. For this purpose, an accelerator with cutting-edge technology is to be built into the existing 2.3-kilometre-long PETRA ring tunnel.

If implemented, this large-scale project would not only create the world´s best synchrotron radiation source in Hamburg´s west, but – in conjunction with the interdisciplinary research facilities and innovation laboratories on the DESY campus and the future Science City Bahrenfeld – a globally unique beacon of research.

The Technical Design Report (TDR) for PETRA IV, which is due by the end of 2022, is an important milestone for the implementation of the overall project. It contains the technical construction plans of the accelerator, the X-ray beamlines and the surrounding infrastructure. It also outlines the construction measures and their sequence, with reliable information on the expected project costs. The TDR is the basis for the application for funding of the overall project.
