The University of Kassel and Helmholtz-Zentrum Berlin are setting up a joint laboratory for the use of artificial intelligence, where they will be developing new experimental methods and improving the analysis of data from experiments performed at BESSY II.
Every year, nearly 3000 user groups from around the world visit the electron storage ring BESSY II to study an immense variety of materials using the brilliant X-ray light the ring generates. “In the research of current scientific problems, at BESSY II for example, so much data accumulates that it can barely be analysed using conventional analytical programs. In the Joint Lab, we will be developing and employing methods of artificial intelligence to do this analysis. These methods should even allow us to think up entirely new test scenarios in other scientific and technical areas that have always seemed beyond our analytical capabilities in the past,” says Prof. Dr. Arno Ehresmann, the vice president of the University of Kassel, who is also responsible for research funding.
HZB and the University of Kassel recently signed a joint cooperation agreement to set up the Joint Lab Artificial Intelligence Methods for Experiment Design (AIM-ED). A Joint Lab is a medium- to long-term form of cooperation established between the Helmholtz Association and universities. “We are pleased to be able to combine the expertise in artificial intelligence of the University of Kassel and Helmholtz-Zentrum Berlin in this way, for working on groundbreaking solutions together,” says Prof. Ehresmann.
One institute involved in the Joint Lab is the Kassel Research Center for Information System Design (ITeG). “There will also be several particularly strong research groups from the physics department working on the application of AI methods for the design, analysis or optimisation of experiments, including within a DFG Special Research Area,” Prof. Ehresmann says. The Intelligent Embedded Systems Group will also be involved, under the direction of Prof. Dr. Bernhard Sick, who has long been working intensively in the field of machine learning and artificial intelligence.
There are many synergies arising from the newly founded Joint Lab, emphasises Dr. Gregor Hartmann, a supervising researcher at Helmholtz-Zentrum Berlin. “The experiments at BESSY II generate immense amounts of data, where not only the volume of the data but also the complexity and understanding of their creation are decisive for good analysis.” HZB has great expertise in beamline development, and Prof. Ehresmann’s workgroup is contributing its expertise in detectors from the perspective of a long-term BESSY II user. The broad range of artificial intelligence methods covered by Prof. Bernhard Sick’s team will allow the best possible analysis of data. “I am very much looking forward to the intensive and exciting cooperation in this Joint Lab,” says Hartmann.
- The twisted nanotubes that tell a storyIn collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data based on quasiparticles called magnons, rather than electrons.
- Ernst Eckhard Koch Prize and Innovation Award on Synchrotron Radiation 2025At the 27th BESSY@HZB User Meeting, the Friends of HZB honoured the dissertation of Dr Enggar Pramanto Wibowo (Friedrich-Alexander University Erlangen-Nuremberg). The Innovation Award on Synchrotron Radiation 2025 went to Prof. Tim Salditt (Georg-August-University Göttingen) and Professors Danny D. Jonigk and Maximilian Ackermann (both, University Hospital of RWTH Aachen University).
- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.
