Three days for exchange between Users of BESSY II and BER II and HZB-scientists
Usermeetings offer a platform for exchange and communication. © M-Setzpfand/HZB
The Seventh Joint BER II and BESSY II User Meeting will take place at WISTA, Berlin-Adlershof on December 9th and 10th, the neutrons session are at Berlin-Wannsee on December 11th. The Verein Freundeskreis Helmholtz-Zentrum Berlin e.V. will bestow the Innovation Award and the Ernst-Eckart-Koch Prize. Public highlights are a science slam on Wednesday, 18:30 and the public lecture by David Cahen on the power of science to bridge ideological differences (“Science: Bridge over troubled water“, Thursday 17:00). The public lecture and the science slam are open for everybody.
Wednesday 9th December: WISTA-Centre, Adlershof
- The Synchrotron Day starts at 14:00: HZB scientist will present new developments at BESSY II, followed by the Young Scientists Session and for the first time:
- a HZB Science Slam (18:30).
Thursday 10th December: WISTA-Centre, Adlershof
- The Science Day starts with a keynote lecture by Petra de Jongh (University Utrecht) about the “stability of supported transition metal catalysts”.
- The next sessions are dedicated to short oral presentations about (user)-research at BESSY II, ranging from the analysis of spins in diverse materials, protein crystallography to the geology of meteorites.
- The Innovation Award and the Ernst-Eckart-Koch Prize will be awarded by the Verein Freundeskreis Helmholtz-Zentrum Berlin e.V. during the afternoon.
- At 17:00 David Cahen, head of the optoelectronic materials group at Weizmann Institute of Science, will give a public lecture, sharing his thoughts on science as a bridge over huge divides such as ideologies.
- The Poster Session accompanied by the traditional “Berlin Buffet”, kindly sponsored by the companies represented in the industrial exhibition, will conclude the evening.
Friday, 11th December: LMC-Campus, Wannsee:
- The Neutron day begins with a Neutron session, where HZB scientists will give short overviews about new options and improvements, including the presentation of the High Field Magnet.
- In the Young Scientists Session and during the Poster Session, user research will be presented.
The public lecture and the science slam are open for everybody.

- Optical innovations for solar modules - which are the most promising?In 2023, photovoltaic systems generated more than 5% of the world’s electrical energy and the installed capacity doubles every two to three years. Optical technologies can further increase the efficiency of solar modules and open up new applications, such as coloured solar modules for facades. Now, 27 experts provide a comprehensive overview of the state of research and assess the most promising innovations. The report, which is also of interest to stakeholders in funding and science management, was coordinated by HZB scientists Prof. Christiane Becker and Dr. Klaus Jäger.
- BESSY II: Magnetic ‘microflowers’ enhance magnetic fields locallyA flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.
- Perovskite solar cells: New Young Investigator Group funded by BMBF at HZBIn the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.
