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: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- New instrument at BESSY II: The OÆSE endstation in EMILA new instrument is now available at BESSY II for investigating catalyst materials, battery electrodes and other energy devices under operating conditions: the Operando Absorption and Emission Spectroscopy on EMIL (OÆSE) endstation in the Energy Materials In-situ Laboratory Berlin (EMIL). A team led by Raul Garcia-Diez and Marcus Bär showcases the instrument’s capabilities via a proof-of-concept study on electrodeposited copper.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
