At the end of August, the Senator for Research, Health, and Long-Term Care, Dr Ina Czyborra, together with the State Secretary for Science, Dr Henry Marx, ended her summer tour with a visit to HZB in Adlershof. She publicly declared her political support for the new construction of BESSY III.
Ina Czyborra took an afternoon for intensive discussions with scientists and BESSY II light source. The focus was on the versatility of this large and powerful research infrastructure: from the decoding of protein structures to groundbreaking innovations in the field of renewable energies.
Political support for BESSY III
A central topic was the successor source BESSY III (More information). HZB is planning a 4th generation light source with integrated laboratories, which is to be embedded in the Berlin-Adlershof research campus. The Senator expressly supports this project:
"Once again, I have seen cutting-edge research that is attracting worldwide attention. Adlershof has everything that makes Berlin a unique location - science, research and business in proximity, cooperating and benefiting from each other. [...] This makes it even more important to set the course in the Senate's budget deliberations, which begin in September, to ensure that Berlin remains a centre of cutting-edge research with international appeal in the future. Incidentally, we also need BESSY III for this. The continuation of BESSY is of immense importance for Berlin as a research location. That is why I will do everything I can to ensure that this project is continued."
"We are extremely pleased about such a clear commitment to our plans to build BESSY III in Berlin-Adlershof," says Prof. Bernd Rech, Scientific Director of HZB. "The exchange with the Senator for Science underlines how important the dialogue between science and politics is. Especially when it comes to further advancing cutting-edge research in Berlin!"
- BESSY II: High-resolution insights into individual biomolecules and catalystsVery small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline with a newly validated and improved technique: The nanoscale infrared spectroscopy (s-SNOM) with ultra-thin silicon-based membranes. An international team demonstrated after an initial proof of concept, that high-resolution (a few tens of nanometres) nano-IR measurements reliably match expected far-field IR spectra in an aqueous environment. This methodological advance provides a solid foundation for studying biomaterials or observing catalytic processes in a liquid environment.
- New method shows how molecular switches are influenced by their neighborsResearchers at Friedrich Schiller University Jena and the Helmholtz Centre Berlin (HZB) have, for the first time, been able to directly observe how the environment surrounding a molecular switch influences its electronic structure. Molecular switches are molecules that can be switched between two states by external influences such as changes in temperature—similar to a switch with the positions »On« and »Off«. Such molecules are being investigated as potential building blocks for future data storage devices or sensor materials. Using magnetic-field-dependent terahertz spectroscopy, the researchers have now, for the first time, been able to distinguish whether neighbouring molecules in a material are in the same or different states. The results have been published in the journal »Angewandte Chemie International Edition«.
- BESSY II is back in operation after maintenance shutdownOn 7 September 2026, BESSY II was set into operation after a four-week shutdown. BESSY II is scheduled to resume full user operation on 22 September.
