More than 300 Scientists at SRF 2009 in Berlin
International Conference on RF-Superconductivity and Accelerator Physics was a great success!
International Conference on RF-Superconductivity and Accelerator Physics was a great success! The HZB hosted an important international conference, SRF 2009 (International Conference of Radiofrequency Superconductivity) from September 20 to 25. Professor Dr. Anke Rita Kaysser-Pyzalla welcomed the interested scientists in her opening speech at dbb Forum in Berlin. The number of attendants exceeded all expectations. More than 300 scientists took advantage of this opportunity to discuss the latest results in SRF research and technology development.
RF superconductivity has evolved over the last decades into the enabling technology for many accelerators for particle physics, nuclear physics and, increasingly, light sources. The European Free-Electron Laser (XFEL) in Hamburg and the recently commissioned Spallation Neutron Source (SNS) at Oak Ridge, USA are exciting examples of the varied applications of SRF.
The SRF 2009 was organised by HZB in cooperation with the Forschungszentrum Dresden - Rossendorf. In Rossendorf, 13 tutorial sessions were held from 17th to 19th of September. Notable professionals passed on their extensive knowledge and experience in the field of SRF to about 90 participating scientists.

- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- Spintronics: A new path to room temperature swirling spin texturesA team at HZB has investigated a new, simple method at BESSY II that can be used to create stable radial magnetic vortices in magnetic thin films.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
