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.

- 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.
