ANKA Karlsruhe is a synchrotron radiation facility located in Karlsruhe, Baden-Württemberg, operated by the Karlsruhe Institute of Technology (KIT). It serves as a mid-energy storage-ring light source that provides synchrotron light for interdisciplinary research in physics, chemistry, biology, materials science, and engineering. The facility supports national and international user communities and integrates with European research infrastructures and industrial partners.
ANKA Karlsruhe opened operation in 2000 following construction driven by scientific planning at Forschungszentrum Karlsruhe and later integration into Karlsruhe Institute of Technology. The machine and laboratory complex were developed during a period of synchrotron expansion that included facilities such as ESRF, SLS, and SOLEIL, reflecting European investments in photon science. Throughout the 2000s and 2010s ANKA underwent upgrades in accelerator technology influenced by developments at DESY, CERN, and Max Planck Society laboratories. Regulatory and institutional milestones linked ANKA to national programs including initiatives associated with the Federal Ministry of Education and Research and coordination with the Helmholtz Association. The facility has hosted visiting researchers from institutions such as University of Heidelberg, TU München, Universität Stuttgart, MPI for Solid State Research, and corporate partners including BASF, Siemens, and Bosch.
ANKA's infrastructure centers on a storage ring and injector complex influenced by accelerator concepts developed at Institut Laue-Langevin, GSI Helmholtzzentrum für Schwerionenforschung, and Paul Scherrer Institut. The storage ring operates at intermediate energy optimized for soft X-ray to hard X-ray production, employing insertion devices like undulators and wigglers similar to hardware from Elettra and BESSY II. Injector systems include a booster synchrotron and a linac modeled on designs from DESY Hamburg and CEA Saclay. Beam diagnostics and control systems incorporate technology advances from SLAC National Accelerator Laboratory, Argonne National Laboratory, and Fermi National Accelerator Laboratory. Accelerator physicists at ANKA collaborate with teams from CERN Accelerator School and European XFEL for machine studies and upgrade planning.
ANKA supports multiple beamlines covering soft X-ray, tender X-ray, and hard X-ray regimes, drawing comparators such as Diamond Light Source, PETRA III, and ALBA. Beamline endstations host spectroscopy, diffraction, imaging, and scattering techniques used by researchers from University of Cologne, RWTH Aachen University, Freie Universität Berlin, and Leibniz Institute for Solid State and Materials Research Dresden. Specialized stations enable micro- and nano-focused X-ray fluorescence, X-ray absorption spectroscopy (XAS), X-ray photoelectron spectroscopy (XPS), tomography, and small-angle X-ray scattering (SAXS), with detector systems influenced by developments at European Synchrotron Radiation Facility and IOP. Sample environments accommodate in situ and operando setups relevant to groups from Max Planck Institute for Polymer Research, Fraunhofer Society, and Helmholtz-Zentrum Berlin.
Research at ANKA spans condensed matter physics, catalysis, biomaterials, cultural heritage, and semiconductor research, engaging investigators from University of Freiburg, University of Tübingen, Karlsruhe University Hospital, and German Cancer Research Center. Applications include structural biology studies comparable to work at EMBL, materials characterization parallel to projects at ISIS Neutron and Muon Source, and energy materials research linked to programs at Fraunhofer Institute for Solar Energy Systems ISE. Industrial projects with companies such as Evonik and ThyssenKrupp address coatings, corrosion, and additive manufacturing. Cultural heritage collaborations involve museums and archives akin to partnerships seen at British Museum and Rijksmuseum.
ANKA participates in national and European networks including interactions with European Commission framework programs, coordination with League of European Accelerator-based Photon Sources, and partnerships with Deutscher Akademischer Austauschdienst for training exchanges. Funding streams have included allocations from Baden-Württemberg Ministry of Science, Research and Arts, the Federal Ministry of Education and Research, and programmatic support from Helmholtz Association and university budgets of Karlsruhe Institute of Technology. Collaborative agreements link ANKA to consortia involving Max Planck Society, Fraunhofer Society, and international partners such as CERN and SLAC for joint projects, technology transfer, and joint calls.
ANKA provides user access via proposal-driven beam time allocations, training courses for beamline techniques, and internships that mirror programs at European Synchrotron Radiation Facility and EMBL. Educational outreach engages students from KIT, University of Applied Sciences Karlsruhe, and international visitors supported through exchanges with DAAD and doctoral supervision in collaboration with institutes like MPI for Polymer Research and Karlsruhe University Hospital. User support services include proposal assistance, sample preparation facilities, and remote access options inspired by practices at Diamond Light Source and SOLEIL.
ANKA has contributed to high-impact publications in journals where authors are affiliated with Nature Communications, Physical Review Letters, Journal of Synchrotron Radiation, Angewandte Chemie, and ACS Nano, and has influenced technology transfer projects with industrial partners such as BASF and Siemens. Notable achievements include advances in nanoparticle characterization, operando studies of battery materials paralleling breakthroughs at Argonne National Laboratory, and imaging developments that informed conservation projects similar to those undertaken with British Museum and Rijksmuseum. The facility's role in regional research ecosystems has strengthened ties among KIT, regional universities, and research institutes across Germany and Europe.
