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.

On Thursday, March 15, 2018 the 8th International Masterclass took place at FAIR and GSI. 20 high-school students were invited to become a scientist for a day and analyse data from the ALICE experiment at the LHC accelerator at CERN in Geneva. GSI has had a major part in the construction and the scientific programme of ALICE from the beginning.

FAIR at BSBF2018
Eighteen of the world’s largest research facilities gathered to create Big Science Business Forum to present their offers to European industry. BSBF was a one-stop shop for companies from all over Europe, where Big Science facilities could give them insight into our future investments and purchases in just one location over the course of a few days.

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...
