GSI Helmholtzzentrum für Schwerionenforschung

GSI Helmholtzzentrum für Schwerionenforschung operates a unique 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.

New record: Extremely slow ions at CRYRING@ESR open up new pathways for astrophysics

An international research team has achieved an important milestone for astrophysics at GSI/FAIR in Darmstadt: In the CRYRING@ESR storage ring, scientists were able to measure nuclear reactions at extremely low energies for the first time, mirroring the conditions inside stars. This novel experimental approach lays the foundation for decoding the formation of elements in the universe with even greater precision in the future.

A fascination for research — Sixty-nine girls explore GSI/FAIR on Girls’ Day 2026

Girls’Day at GSI/FAIR was again a huge success this year. Sixty-nine schoolgirls aged eleven to seventeen participated and explored the international research center, the accelerator facilities and experiments, as well as the technical infrastructure. Girls’Day is a nationwide event designed to encourage girls to learn about careers where women have traditionally been underrepresented.

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...
