GSI Helmholtzzentrum für Schwerionenforschung

GSI Helmholtzzentrum für Schwerionenforschung operates a unique large-scale accelerator for heavy ions. Researchers from around the world use this facility for experiments that help them make fascinating discoveries in basic research. In addition, they continually develop new and impressive applications.

The experimental collaboration SPARC (a part of APPA) and GSI teams successfully tested the beam transport from the existing GSI Experimental Storage Ring (ESR) to the first FAIR-storage ring CRYRING@ESR, which is being installed on the GSI premises.

Creating and managing one’s own research group for the first time and meanwhile being integrated within a renowned international working environment, gathering teaching experience, and also benefiting from the outstanding infrastructure of a major research center—this is the dream of every young scientist. For the Young Investigators Groups in the Helmholtz-funded research program of the same name, it’s no longer a dream—it’s a tangible reality. In our brochure "Successful Support for Young Academics – The Helmholtz Young Investigators Groups at GSI" we introduce our Young Investigators Groups and their leaders to you in detail.

FAIR – the future accelerator facility

In the next few years the new international accelerator facility FAIR, one of the largest research projects worldwide, will be erected at GSI. At FAIR an unprecedented variety of experiments will be possible. Thereby physicists from all around the world will be able to gain new insights into the structure of matter and the evolution of the universe from the Big Bang to the present.

Cancer Treatment with Ion Beams

GSI is the birthplace of a new form of cancer treatment. This development was the result of many years of research in conjunction with GSI’s large ion-beam accelerator system. The advantage of this new treatment modality is that the ion beam selectively damages tumor tissues while sparing the surrounding healthy tissues. More...


The Creation of New Elements

Chemical elements are produced in stars and stellar explosions. Elements are the building blocks of all materials that surround us – including every atom of our bodies. The universe is also home to a large number of atoms that do not occur on earth. One of the key tasks of the researchers at GSI is to attempt to create previously unknown elements. More...
