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.

Joining forces for cancer research: TRON and GSI/FAIR study combination of heavy ion therapy and mRNA vaccine
Heavy ion synchrotron SIS18 – exterior view
It could be a new, promising combination of two therapeutic approaches and a key to better combating advanced-stage cancer. Two strong partners have joined forces to explore this possibility: The biopharmaceutical and translational research institute TRON in Mainz with its highly specialized oncology research and the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt with its worldwide unique accelerator facilities and the cancer therapy with ion beams developed here. Researchers from…

Ghost particles on the scales
Targets used in the experiment
What is the mass of a neutrino at rest? A team led by the department of Klaus Blaum, Director at the Max Planck Institute for Nuclear Physics in Heidelberg, with the participation of Christoph Düllmann's working group at Johannes Gutenberg University Mainz (JGU), the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, and the Helmholtz Institute Mainz has now made an important contribution to the “weighing” of neutrinos as part of the international ECHo collaboration. Using the…

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...
