1200 accelerator physicists from around the world meet in Dresden
The graduate students Jens Vöker and Christoph Kunert received a IPAC grant and presented their work on a student poster sesson.

The world’s largest particle accelerator conference is being held in Germany for the first time, with around 1200 scientists expected to visit the Saxon capital Dresden from 15 to 20 June. The 5th international conference IPAC is the place for experts to share the advancements they have made in developing particle accelerators and their components.
Experiments with accelerated particles have yielded countless valuable insights for science and mankind. They will forever be a part of modern research. Producing these coveted particles requires a reliable accelerator. The demands on these large machines are constantly growing as researchers wish to gain a deeper understanding of the structure and dynamics of materials, for example, using increasingly intense beams and ever shorter light pulses. Yet, materials research is just one aspect – the range of uses for particle accelerators is extremely wide and is reflected by the range of topics on the IPAC agenda: from future accelerator projects, to alternative concepts, to use in cancer therapy. The conference is being hosted by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). Helmholtz-Zentrum Berlin, with its competence in accelerator physics, is supporting the local organization of the conference.
Helmholtz-Zentrum Berlin is taking this opportunity to present the concept BESSY-VSR, the most important advancement on the electron storage ring BESSY II, to a large community of specialists. The HZB scientists have also summarized on a number of posters the progress in the development of a prototype for an energy recovery linac (ERL), BERLinPro, as well as in undulator development. Following the conference, 50 interested participants will be visiting the electron storage ring BESSY II, the Metrology Light Source (MLS) and the test laboratory for superconducting cavities (HoBiCaT) and learning about the experimental possibilities at HZB.
The international conference aims especially at promoting new, young talents in accelerator physics and giving them the opportunity to participate in this important exchange platform. In total, 90 students from around the world have received “IPAC Grants”. These grants cover their conference fees and allow them to participate in a junior scientist poster exhibition. From Helmholtz-Zentrum Berlin, Christoph Kunert (Proton Therapy) and Jens Völker (Institute for Accelerator Physics) have each received a grant. In the conference’s local organization committee, Stefanie Kodalle (Communication) is supporting the smooth proceedings of the conference as Presentation Manager.
The accelerator conference also featured a free evening lecture for the interested public: On 15 June, Dresden scientist Professor Wolfgang Enghardt presented information about the novel cancer therapy with particle beams and about accelerators in medicine.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
- Hydrogen: Breakthrough in alkaline membrane electrolysersA team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the catalytic processes in detail using operando measurements, and a theory team (USA, Singapore) provided a consistent molecular description. In Freiburg, prototype cells were built using a new coating process and tested in operation. The results have been published in the prestigious journal Nature Catalysis.
