DESY is one of the world's leading accelerator centers. Researchers use DESY's large facilities to explore a variety of microscopic worlds, from the interactions of tiny elementary particles and the behavior of novel nanomaterials to biomolecular processes essential to life. The accelerators and detectors developed and manufactured by DESY are unique research tools. These facilities produce the world's most intense X-rays, accelerate particles to record energy and open whole new Windows on the universe.
DESY conducts diverse research in four areas, namely accelerator, photon science, particle physics and astroparticle physics. Scientists working here search for the smallest building blocks of matter that make up the world, develop innovative high-tech materials, and search for new mechanisms of action for future drugs. As one of the largest research centres in Germany, DESY conducts basic research, creating new knowledge and conceptual approaches. This research is the foundation for future challenges: issues such as energy supply, climate protection and healthcare require long-term thinking, sustainable solutions and new technologies.
DESY attracts more than 3,000 guest researchers from more than 40 countries each year, providing specialized training for many studies; DESY works with industry and business to promote new technologies that benefit society and encourage innovation. DESY is committed to fundamental research on the structure and function of matter, preparing the world with the necessary knowledge base. The Center conducts top-level international research on the fundamental relationships, structure and function of matter, seeks to build the knowledge base needed to address the enormous and pressing challenges facing society, science and the economy, and continues to expand its knowledge in research areas such as photonic science, particle and astroparticle physics, and accelerator physics. Obtain results from synchrotron radiation sources, X-ray lasers, particle accelerators, detectors and observatories, and carry out related research and development work.
