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.
- Technology Transfer Prize Ceremony 2025This year’s Technology Transfer Prize Ceremony will take place on October 13 at 2 pm in the Lecture Hall, BESSY II Building, Adlershof.
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
