Helmholtz-Zentrum Berlin

Helmholtz-Zentrum Berlin (HZB) is a research centre that focuses on photon science and materials research using large‑scale accelerator facilities. Its primary mission is to provide scientists with access to synchrotron radiation and related experimental techniques for investigating the structure and function of matter. Researchers at HZB study topics ranging from solar energy materials and catalysis to quantum materials and biological macromolecules. The centre offers beamlines, laboratories and support services that enable both fundamental and applied investigations. Users come from universities, other research institutions and industry across Germany and abroad.

HZB operates two main campuses, one in the Adlershof district of Berlin and another in Wannsee, together housing several hundred employees including scientists, engineers and technical staff. The facility provides access to the BESSY II synchrotron light source, which delivers photons ranging from infrared to hard X‑rays for a variety of experimental stations. Through its user programme, HZB serves thousands of visiting researchers each year, contributing to national and international scientific projects. The centre also collaborates closely with Helmholtz Association partners and external organisations to develop new instrumentation and methods. These activities give HZB a broad reach within the German research landscape and beyond.

As a member of the Helmholtz Association, HZB benefits from a strategic focus on solving grand challenges in energy, information and matter. Its distinguishing attribute is the operation of BESSY II, a third‑generation synchrotron that provides exceptionally bright and stable radiation for advanced spectroscopic and imaging techniques. The centre has developed particular expertise in soft X‑ray absorption spectroscopy, resonant inelastic scattering and time‑resolved pump‑probe experiments. These capabilities enable detailed insight into electronic and structural dynamics of materials relevant to renewable energy technologies. HZB’s reputation for high‑quality beamline instrumentation and user support makes it a preferred destination for cutting‑edge photon science research.

Structurally, HZB is a non‑profit research institute that is legally independent but financially supported by the German federal government and the states of Berlin and Brandenburg. It is governed by a board of trustees and scientific council typical of Helmholtz Association centres, ensuring alignment with the association’s research programme. The centre does not have a commercial parent or subsidiary, but it engages in knowledge exchange with industry and other research organisations through joint projects and contract research. Funding comes from a combination of core institutional support, competitive grants from European and national programmes, and fees for user access to its facilities. This structure allows HZB to maintain long‑term operation of its large‑scale facilities while pursuing innovative research directions.
