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.
- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- Spintronics: A new path to room temperature swirling spin texturesA team at HZB has investigated a new, simple method at BESSY II that can be used to create stable radial magnetic vortices in magnetic thin films.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
