Three-day exchange at User Meeting
From December 12 to 14, more than 400 users of HZB's BER II and BESSY II large-scale equipment met up to discuss the current state of technology and exchange their views on pressing scientific issues. Two of the highlights were Science Day on December 13 and Neutron Day on December 14, both held at the Bunsensaal in Berlin-Adlershof. Both days, the focus was on instrumentation. Participants were able to learn about new technologies and advances in large-scale equipment instrumentation. Science Day featured the many scientific achievements that have been made thanks to BESSY II and BER II.
Holger Dau of the Free University Berlin delivered the keynote lecture titled "X-ray spectroscopy in solar-fuels research - from biology to inorganic catalysts." EMPA Zurich's Andreas Züttel gave the public lecture titled "What we learn from history to master the future energy challenge." The two lectures impressively highlighted the tremendous potential of large-scale equipment in energy research.
Science Day awards
On December 13, two awards were given out by the Helmholtz Centre Berlin Circle of Friends. Recipients of this year's 4000 Euro Synchrotron Radiation Innovation Award included DESY's and European X-FEL's Gianluca Geloni, Vitali Kocharyan, and Evgeni Saldin as well as Paul Emma of the Lawrence Berkeley National Laboratory. The four physicists were being recognized for their development of a "self-seeding" protocol that significantly improves free-electron laser technology.
The Ernst-Eckhard-Koch Award for excellence in doctoral-level research in the amount of 2500 Euros went to up-and-coming physicist Dr. Daniil Evtushinsky of the Leibniz Institute for Solid Body and Materials Research in recognition of his work on band-structured and fermi areas of a new class of two-dimensional, high-temperature superconductors.
The HZB User Committee's Best Poster Award went to Christian Caspers of the Jülich Research Centre for the skillful presentation of his work on "Magnetic Oxides EuO Thin Films on Surface Passivated Silicon for Silicon Spintronics."
240 posters, 51 vendors
During the poster session in BESSY experimental hall, a total of 240 posters documented the work done by both HZB and external researchers using the HZB research facilities, with topics ranging from the life sciences and basic physics research to applied research on industrial materials. In addition, five satellite symposia sought to answer pertinent questions on neutron spectroscopy, crystallography, and related topics.
As in previous years, the user meeting featured a well-attended industry exhibit with 51 vendors of synchrotron spectroscopy and neutron diffraction experimental equipment showcasing a broad range of state-of-the-art products. Thanks to the vendors' generous financial support, the lavish "Berlin Buffet" on Thursday night, which offered yet another chance for conversation and networking, attracted many visitors. The organizers would like to thank Adlerhof con.vent, WISTA Management GmbH's event planners, for organizing the industry exhibit.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- Confirmed figures for the first time: Investments in BESSY are worthwhile for Berlin and GermanyAn impact analysis by DIW Econ demonstrates the scientific and economic value of BESSY II. Every euro invested yields three euros for Germany and as much as ten euros for the State of Berlin. Furthermore, the study provides an economic forecast for the construction of BESSY III.
The impact analysis was presented on 3 September 2026 to Dr Henry Marx, State Secretary for Science and Research in the Berlin Senate. He supports the investment and is a strong advocate for BESSY III. - Detailed insights at BESSY II into the oxidation processes of copperBefore pure copper oxide builds up, complex superstructures such as ‘29’CuxO, are formed. The new results on the '29' CuxO superstructure have relevance for catalyst research and corrosion protection in the development of safe copper containers for nuclear waste repositories.
