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.
- Only at BESSY II worldwide: IR nanoscopy at very long THz wavelengthsThe team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.
- Ultrafast demagnetisation - Thinner iron, stronger effectThe thinner an iron film, the more easily it can be demagnetised by a laser pulse. Researchers at the University of Duisburg-Essen, working with Helmholtz-Zentrum Berlin and other partners, have discovered why: the key lies in the magnetic order at the material's interfaces. In the long term, these findings could contribute to the development of new technologies for magnetic data storage. The results have been published in the scientific journal Advanced Science.
- Spin waves inside a nano-oscillator imaged for the first timeFor the first time, researchers have directly imaged the magnetisation dynamics inside a spin Hall nano-oscillator — a nanoscale device that converts direct current into tunable microwave signals and is a promising building block for energy-efficient wireless communication and brain-inspired computing. A Swedish–German team led by the University of Gothenburg and Helmholtz-Zentrum Berlin (HZB) achieved this using time-resolved scanning transmission X-ray microscopy at the MAXYMUS instrument at BESSY II. The results, now published in Advanced Materials, reveal spin-wave features that had escaped previous, indirect measurement techniques.
