44 Cluster Report Optics and Photonics – Optical Analytics The Nanometre Optics and Technology Department at HZB was formed in 2010 from the former BESSY Optics Group and the Microtechnology User Centre (AZM). It combines the internationally recognised expertise of HZB in the design, manufacture, and measurement of optics for short wavelengths. index_de.html DESY Zeuthen, a branch of the Deutsches Elektronen-Synchrotron in Hamburg, is located in the southeastern outskirts of Berlin. The scientists at the site are not only involved in numerous international astrophysical projects. Zeuthen is also where important components for the main DESY site are developed. The new X-ray light source European XFEL in Hamburg offers unique research conditions for the analysis of physical, chemical, and biological processes in highest spatial and temporal resolution. Large single crystals are produced in this optical zone melting furnace. © M. Setzpfandt/HZB The CoreLab for Quantum Materials provides a range of methods and instruments for the synthesis and investigation of new quantum systems for energy and information technology. The instrumentation has many applications, including many other substance classes and questions. The CoreLab makes the instruments available to all HZB scientists, external researchers, and commercial users. index_en.html The Ultra-fast Dynamics in Condensed Matter at the University of Potsdam Working Group is affiliated with HZB. The focus of research here is on the electronic properties of materials, which are expressed properties such as ferroelectricity, optical absorption, and the coherent mixture of electromagnetic waves. The University of Potsdam is also home to the Laboratory for Electron Microprobe Analyser (EMPA). This allows the non-destructive examination of the chemical composition of minerals and glasses in the micrometre range. X-rays can be used to produce concentration maps of individual elements. The Analytical X-Ray Physics Working Group at TU Berlin in Charlottenburg (Prof. Birgit Kanngießer) is investigating and developing methods of X-ray spectroscopy for applications in the life sciences and in materials science. This will allow, for example, chemical compounds and oxidation states to be determined using X-ray emissions (XES) and absorption methods (XAFS). The main aim of the research is to bring established methods from the synchrotron into a normal laboratory and thus make them accessible for a broader use. Another focus of the Kanngießer working group is X-ray microscopy. The short wavelength of X-ray radiation can achieve particularly high resolutions. In cooperation with the Remagen University of Applied Sciences, a system with a spatial resolution of less than 30 nm has been set up at the Hamburg synchrotron PETRA III. The system enables spectroscopic and tomographic measurements. In addition to material science research, a joint project with the Charité is also investigating in vitro biomedical samples at the cellular level.

Cluster Report Optics and Photonics – Optical Analytics 45 The BLiX is located at the endowed chair for analytical X-ray physics held by Prof. Birgit Kanngießer. The aim of the development work is to bring established methods from the synchrotron into a normal laboratory. The potential applications range from geology and environmental sciences to biomedicine. With such innovative labs, TU Berlin is seeking to create institutions in which university and non-university research institutes can collaborate with companies on innovative products. As part of MBI, a member of the Leibnitz Association, the BLiX also functions as a Leibniz application laboratory. An important focus of optical analytics in Berlin are the city’s laboratories for research, testing, and standards, above all the National Metrology Institute of Germany Physikalisch-Technische Bundesanstalt (PTB) and the Federal Institute for Materials Research and Testing Bundesanstalt für Materialforschung und -prüfung (BAM). Diatom as seen with the X-ray microscope LTXM (Laboratory Transmission X-ray Microscope) at TU Berlin © TU Berlin At the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), a major focus is on the investigation of particularly short pulses. The shortest pulses currently accessible in experiments are in the attosecond range. This is much shorter than a single vibration of visible light. Accordingly, such pulses can only be generated at much shorter wavelengths, typically by high-order harmonic generation (HHG). The researchers at the MBI are using such pulses in the EUV and X-ray ranges to investigate the structure- and time-dependent dynamics of electrons in atoms, molecules, and solids. Various spectroscopic methods up to X-ray holography are therefore being researched. The two PTB departments in Berlin-Charlottenburg address issues related to thermometry, radiometry, medical physics, mathematics, and information technology for metrology. At Berlin-Adlershof, PTB operates the MLS (Metrology Light Source) electron storage ring for calibrations from the infrared (THz) to extreme ultraviolet (EUV) and also uses the BESSY II electron storage ring. sites-in-berlin.html BAM has its own department for radiological processes, which develops, applies, validates, and certifies radiological procedures with X-, gamma-, and terahertz (THz) rays. To this end, BAM is developing new two- and three-dimensional digital measuring and testing methods (computer laminography, tomosynthesis, and computer tomography) for industrial and security applications. Together with TU Berlin, MBI operates the Berlin Laboratory for Innovative X-ray Technologies (BLiX). The equipment includes the BLiX X-ray microscope with a highly brilliant laser plasma source. This allows time-resolved and single-shot (NEXAFS) measurements in a range of up to 1 keV. The Department of Micro Non-Destructive Testing (ZFP) is developing and evaluating non-destructive testing methods for the detection of structures and defects in the micrometre range and smaller. This is achieved with high-resolution X-ray imaging methods and quantitative 3D characterisation of the material microstructure. BAM offers special expertise in computer tomography and X-ray scattering which complement the city’s industrial and academic landscape. In addition, material characterisation is the keyword for the development of competencies and apparatus such as tensile or high-temperature tests in CT and refraction devices.
