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.

Therapy – Treatment Facility at GSI and FAIR
GSI/FAIR is actively involved in the charity cycling event "Tour der Hoffnung" for the benefit of children suffering from cancer and leukemia. When the nationwide known fundraising event stops at the Bürgermeister-Pohl-Haus in Wixhausen on August 12, 2022 at 3 p.m., representatives of GSI/FAIR and the Association for the Promotion of Tumor Therapy with Heavy Ions will be there. They will inform about cancer therapy with ions and the current state of research, as well as about the activities of…



T-lymphocytes before (left) and after (right) the treatment with X-rays.
Radiation therapy is a proven approach to destroying tumours. However, it is possible that it might be able to do even more in the future – namely stimulate the immune system at the same time and so fight cancer even more intensively. Researchers led by TU Darmstadt and with participation of GSI Helmholtzzentrum für Schwerionenforschung have found that x-rays trigger a calcium signalling cascade in cells of the immune system. The results have now been published in the “Journal of General…



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...
