The future of BESSY

At the end of February 2024, a team at HZB published an article in Synchrotron Radiation News (SRN). They describe the next development goals for the light source as well as the BESSY II+ upgrade programme and the successor source BESSY III.
In autumn 2023, HZB celebrated 25 years of research at the BESSY II light source in Berlin-Adlershof. To continue offering scientists from all over the world the best research opportunities in the coming decades, it is important to have a vision for BESSY II. In addition, many light sources around the world are currently being modernised or even newly built to keep up with the latest research questions and contribute with state-of-the art research infrastructures.
The article "Material Discovery at BESSY" shows the relevance of BESSY light source for the research questions of the future. The HZB team describes the goals of the BESSY II+ upgrade programme. Among other things, the programme aims to expand operando techniques that are of great benefit in developing materials for the energy transition.
BESSY II+ is a bridge between BESSY II and the successor source BESSY III, which is scheduled to go into operation in the mid-2030s. It is set to become the "materials discovery machine": a combination of the extremely bright, soft 4th generation light source, the integrated research campus in Berlin-Adlershof and the quantitative measurement capabilities of the national metrology institute (PTB, Physikalisch-Technische Bundesanstalt) from synchrotron research.
The article has been published in open access and can be read in the journal SRN, which specialises in synchrotron research.

- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- Thin nickel films boost green hydrogen productionUltra-thin nickel oxide coatings can significantly improve the performance of anion exchange membrane (AEM) water electrolysers, a promising technology for producing green hydrogen. This was demonstrated by a team led by HZB scientist Dr. Michelle Browne. The results show that a nickel oxide film only 10 nanometres thick outperformed conventional nickel oxide powder electrodes while using less than 1% of the catalyst material. The study is published in the Journal of Materials Chemistry A,
- Confirmed figures for the first time: Investments in BESSY are worthwhile for Berlin and GermanyAn impact analysis by DIW Econ demonstrates the scientific and economic value of BESSY II. Every euro invested yields three euros for Germany and as much as ten euros for the State of Berlin. Furthermore, the study provides an economic forecast for the construction of BESSY III.
The impact analysis was presented on 3 September 2026 to Dr Henry Marx, State Secretary for Science and Research in the Berlin Senate. He supports the investment and is a strong advocate for BESSY III.
