The Friends of Helmholtz-Zentrum Berlin (HZB) have awarded the Ernst-Eckhard-Koch-Prize 2022/23 to the outstanding PhD thesis of Dr. Xiujie Deng from Tsinghua University in Beijing. The thesis entitled "Theoretical and Experimental Studies on Steady-State Microbunching" was written in the framework of a cooperation between Tsinghua University, HZB and Stanford University at PTB's Metrology Light Source (MLS) in Berlin-Adlershof. According to the prize committee, the breakthrough was achieved in the generation of coherent synchrotron radiation by microbunching of the stored electron beam via interaction with intense laser radiation. The aim of the project is to develop novel, powerful EUV radiation sources for applications in research and industry.

The Ernst Eckhard Koch Prize went to Dr Fredrik Johansson (now Institut des NanoSciences de Paris, CNRS, Sorbonne) for his dissertation at Uppsala University on "Core-hole Clock Spectroscopy Using Hard X-rays - Exciting States in Condensed Matter".
"Overall an exceptional dissertation achievement" said the expert jury, highlighting the number of Johansson’s high-quality scientific publications. "Also impressive is the demonstration of orbital and directional selectivity in ultrafast charge transfer in SnS2 using core-hole-clock," the jury said. Johansson then presented the method in a clear and concise talk: it allows a precise measurement of charge transfer times in different solids and promises deeper insights into solar cells, for example. From 01.10.2020 to 31.8.2021 Fredrik Johansson was a post-doc in the group of Prof. Alexander Föhlisch (University of Potsdam, HZB/BESSY).

The Ernst Eckhard Koch Prize went to Dr. Martin Bluschke, Max Planck Institute for Solid State Research in Stuttgart, who completed his doctorate in 2019 at the Technical University of Berlin. The title of his dissertation is: "Resonant x ray scattering studies of collective electronic states in cuprates and nickelates controlled by isovalent chemical substitution and epitaxial integration". Bluschke has been studying so-called collective states in solids at BESSY II, which are related to the phenomenon of superconductivity.

Dr. Joachim Robert Gräfe from the Max Planck Institute for Intelligent Systems in Stuttgart was recognised for his doctoral dissertation “Statische und dynamische Magnetisierungseigenschaften nanoskaliger Überstrukturen” (static and dynamic magnetisation properties of nano-scale superlattices) at the University of Stuttgart. During his doctoral studies he was able to accomplish the first direct mapping and analysis of spin waves, also referred to as magnons, in nanoscale anti-dot lattices with the help of dynamic X-ray microscopy at GHz frequencies. The experiments took place at the BESSY II MAXYMUS microscope.

Dr. Jan Wernecke, who has since joined the IAV company in Gifhorn, was recognised for his doctorial dissertation “When Size Does Matter: Dimensional Metrology of Nanostructured Layers and Surfaces Using X-Rays” at the Technische Universität Berlin. His doctoral studies were carried out in the BESSY II laboratory of the the Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute. The main task consisted of employing small-angle X-ray scattering for measuring nano-dimensional features on surfaces and thus establish standard metrological data traceable back to the international system of units SI with uncertainties in the range of a few atomic diameters.

The Association of Friends of Helmholtz-Zentrum Berlin awarded during the Seventh Joint BER II and BESSY II User Meeting on 10 December 2015 the 25th Ernst Eckhard Koch Prize for outstanding doctoral theses in the field of research with synchrotron radiation:
Dr. Robert Streubel, who has since become a postdoc at the Lawrence Berkeley National Laboratory, was honored for his doctoral dissertation entitled “Imaging Spin Textures on Curved Magnetic Surfaces” at Technische Universität Chemnitz that dealt with the investigation of three-dimensional magnetic structures by a new combination of X-ray absorption tomography und photoemission microscopy. The measurements were performed at BESSY II and at the ALS using circularly polarized synchrotron radiation within the framework of research projects of the Leibniz-Institut für Festkörper- und Werkstoffforschung Dresden. Part of the well noticed results have already been published in Nature Communications.
