GSI Helmholtzzentrum für Schwerionenforschung GmbH operates a worldwide unique large-scale accelerator for heavy ions. Every year about 1,000 researchers from around the world use this facility for experiments that help them make fascinating discoveries in basic research. The scientific goal is to gain new insights about the building blocks of matter and the evolution of the universe. At GSI for example six new elements have been discovered. In addition GSI scientists develop new applications in medicine and technology, e.g. a new type of tumor therapy using ion beams.
