GSI Helmholtzzentrum für Schwerionenforschung

GSI Helmholtzzentrum für Schwerionenforschung GmbH operates a unique large-scale 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.

In the 11th issue of our GSI magazine "target" we cover the modification of our ring accelerator in preparation for the use with FAIR. Also some of the FAIR components have arrived already at GSI. In our interview trainee Wei-Kang Liu tells us about his experiences in the GSI theory department. And our design engineers explain how to get from an idea to a final product.

The completion of the shell construction for the FAIR accelerator CRYRING@ESR has been celebrated with a roofing ceremony on March 14, 2014. The former FOPI cave in the GSI experimental area has been remodelled to house the ring in the earlier months. The concrete work is now finished. The civil work is carried out by the specialist departments of the division FAIR@GSI together with the GSI plant and facility engineering.

FAIR – Facility for Antiproton and Ion Research

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

Tumortherapie mit Ionenstrahlen

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.

The Creation of New Elements

Erzeugung neuer Elemente

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.
