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.

It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising approaches to follow up such considerations. An international research team led by the Biophysics Department of the GSI Helmholtzzentrum in Darmstadt now has found decisive indications of the possible benefits of artificial hibernation for radiation resistance.



Prof. Hans-Jürgen Wollersheim
Professor Hans-Jürgen Wollersheim has been awarded an adjunct professorship at the University of Delhi for his many years of cooperation with Indian scientists. Since 2004, the GSI researcher has engaged in intensive scientific cooperation with India and was the liaison person for the cooperation with India in the FAIR project as In-Kind Coordinator FAIR@GSI.



Delivery of the coldbox for the FAIR cryo facility
A large heavy goods transport set off from Aschaffenburg to Darmstadt on November 30, 2022. Its destination was the international accelerator facility FAIR (Facility for Antiproton and Ion Research), which is currently being built at the GSI Helmholtzzentrum für Schwerionenforschung. Loaded was the so-called “coldbox”, a steel tank with a length of 18 meters, a height of more than 4.5 meters and a weight of 85 tons. The coldbox is the heart of the cryogenics facility, produced and installed by…



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...
