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.

The ISOLDE experiment faciliy at CERN.
Physicists call the atomic nucleus of tin-100 doubly magic because it simultaneously has two shell closures. Nevertheless, it is very difficult to measure its mass. An international group of scientists at the European research centre CERN (Conseil Européen pour la Recherche Nucléaire) including physicists from GSI Helmholtzzentrum and University of. Greifswald has now succeeded in measuring the precise masses of the indium isotopes 99In, 100In and 101In, thus making it possible to draw…

Screenshot from the vidoeconference — High-school students learn more about GSI/FAIR during Saturday Morning Physics
Approximately 170 high-school students learned about GSI and FAIR this year in the lecture series “Saturday Morning Physics”. The series, organized by the Technical University of Darmstadt, takes place as an online-only event due to the Corona pandemic, as it already did last year. On four Saturdays, the participants quench their thirst for knowledge about current research in physics —last Saturday, a virtual visit to the accelerators and experiments of GSI and FAIR was part of the program.

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...
