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.

Participants Saturday Morning Physics 2024
Around 110 high school students from across Hesse visited the GSI/FAIR campus on Saturday, November 23, for the 25th anniversary of the “Saturday Morning Physics” event series. Through guided tours of the research facilities, the students gained exciting insights into current physics research, explored the existing GSI particle accelerators and experiments and learned about the construction of the international accelerator facility FAIR.



Scene from Anomalie – Crystall Ball Detector
On Thursday, November 21, 2024, starting at 6:00 p.m., GSI/FAIR offers a public screening of the Darmstadt science fiction series “Anomalie” in the lecture hall, Planckstraße 1, 64291 Darmstadt. The series — produced by Darmstadt filmmakers “Tag & Nacht Media” — was filmed in parts at GSI/FAIR. Among other things, the film features the main control room of the GSI/FAIR accelerator facility and the Crystal Ball Detector as a time machine. The event will provide an insight into the series together…



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...
