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.
- Small powerhouses for very special lightAn international team presents the functional principle of a new source of synchrotron radiation in Nature Communications Physics. Steady-state microbunching (SSMB) allows to build efficient and powerful radiation sources for coherent UV radiation in the future. This is very attractive for applications in basic research as well in the semiconductor industry.
- New Method for Absorption Correction to Improve Dental FillingsA research team led by Dr. Ioanna Mantouvalou has developed a method to more accurately depict the elemental distributions in dental materials than previously possible. The used confocal micro-X-ray fluorescence (micro-XRF) analysis provides three-dimensional elemental images that contain distortions. These distortions occur when X-rays pass through materials of different densities and compositions. By utilizing micro-CT data, which provides detailed 3D images of the material structure, and chemical information from X-ray absorption spectroscopy (XAS) experiments conducted in the laboratory (BLiX, TU Berlin) and at the synchrotron light source BESSY II, the researchers have improved the method.
- MXenes for energy storage: Chemical imaging more than just surface deepA new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or intercalated within the MXene electrode (bulk) with high chemical sensitivity. The method was developed by a HZB team led by Dr. Tristan Petit. The scientists demonstrated among others first SXM on MXene flakes, a material used as electrode in lithium-ion batteries.
