All BESSY II instruments reconnected to the network

Thirteen months ago, HZB fell victim to a criminal cyberattack that also took BESSY II light source and the instruments in the experimental hall out of operation. BESSY II was up and running again after just three weeks and the instruments were gradually put back into operation. Now HZB can report some good news: All experimental stations are again integrated into the new IT networks and can record data.
In a task force led by Andreas Jankowiak and Jens Viefhaus, a team led by Ruslan Ovsyannikov succeeded in implementing a new IT infrastructure and a resilient network architecture. This project is now to be firmly established and perpetuated at HZB. The aim is to achieve the full functionality of the BESSY-II user service, to establish new possibilities for remote experiments and better data management.
The project also benefits from the successes of an international cooperation that is developing a new basis for experimental data management at light sources and small labs called Bluesky. With Bluesky, a new type of experimental data acquisition system is being introduced throughout BESSY II (under the leadership of HZB employees William Smith and Simone Vadilonga). It is already in operation at several BESSY beamlines. The introduction of Bluesky at BESSY II is a milestone and has attracted much attention in the scientific community. Several European accelerators are interested in the novel data control system.
HZB is also participating in the Helmholtz project ROCK-IT (Remote, Operando Controlled, Knowledge-driven, and IT-based) to meet the future challenges of data management and the IT structures of large-scale scientific research facilities. The aim is to develop all necessary tools for the automation and remote access of in-situ and operando experiments at synchrotrons. Simplified access to the experiments is a central concern of the user community.
- Spin waves inside a nano-oscillator imaged for the first timeFor the first time, researchers have directly imaged the magnetisation dynamics inside a spin Hall nano-oscillator — a nanoscale device that converts direct current into tunable microwave signals and is a promising building block for energy-efficient wireless communication and brain-inspired computing. A Swedish–German team led by the University of Gothenburg and Helmholtz-Zentrum Berlin (HZB) achieved this using time-resolved scanning transmission X-ray microscopy at the MAXYMUS instrument at BESSY II. The results, now published in Advanced Materials, reveal spin-wave features that had escaped previous, indirect measurement techniques.
- Joint power instead of duplicate structures:Berlin’s research community is further advancing its research excellence by establishing a high-performance, cross-institutional infrastructure for data and AI. With a joint agreement signed on 18 September 2026, the Berlin University Alliance (BUA), the Helmholtz-Zentrum Berlin (HZB) and the Zuse Institute Berlin (ZIB) are paving the way for a joint data science and AI centre in Berlin-Dahlem and Adlershof.
- 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.
