Swedish national synchrotron laboratory MAX IV and Helmholtz-Zentrum Berlin (HZB) with BESSY II light source jointly announce the signing of a 5-year Cooperation Agreement. The new agreement establishes a framework to strengthen cooperation for operational and technological development in the highlighted fields of accelerator research and development, beamlines and optics, endstations and sample environments as well as digitalisation and data science.
The new agreement increases accessibility and overall opportunities for users to conduct advanced materials science investigations at MAX IV and BESSY II in a smooth, integrated manner. Facility collaboration through project-based initiatives may include, among others, reciprocal exchange of knowledge, instrumentation development and usage, data handling, scientific and technical staff, research initiatives, and PhD programme activities.
“Decades of collaboration between Sweden and HZB—rooted in, for example, shared work on energy-relevant materials and enabling methods and technologies—have continually advanced our field. The Cooperation Agreement we sign today gives MAX IV and HZB a solid platform to keep advancing synchrotron science into the 2030s and beyond”, says Olof Karis, Director of MAX IV.
Bernd Rech, Scientific Director at HZB highlights: “The development of new materials is key for a climate-neutral future, we are striving to achieve through science and innovation. I am delighted about the close relationship we have built up between MAX IV and HZB over the years. Thanks to this agreement, we will ensure that bright minds continue to work together, for example to investigate new types of materials and accelerator technologies.”
About the facilities
MAX IV Laboratory is a national large-scale research facility in Lund, Sweden providing scientists with the most brilliant X-rays for research in the materials and life sciences. The synchrotron is hosted by Lund University and is primarily funded by Swedish and international research funders, consortia, and Swedish research universities.

- Cool vaccines in rural Kenya: solar solution has been awarded by UNIn May 2026, Tabitha Awuor Amollo is spending some weeks as a guest scientist at HZB, analysing perovskite thin films at BESSY II. The Kenyan physicist from Egerton University, Nairobi, was recently recognised for her achievements in research and teaching. For the development of a solar-powered refrigeration system for use in rural health centres, she has been awarded the 2026 Organization for Women in Science for the Developing World (OWSD)-Elsevier Foundation Award. An interview on exceptional projects and daily struggles of a scientist. Questions were asked by Antonia Rötger.
- BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteriesAlthough solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
