Success in the Excellence Strategy: GSI and FAIR congratulate closely affiliated universities
GSI and FAIR congratulate the recently selected, closely affiliated universities of excellence. The photo shows Professor Thomas Nilsson during his inaugural lecture as an “affiliate professor” at TU Darmstadt.
The GSI Helmholtzzentrum für Schwerionenforschung and the international accelerator center FAIR warmly congratulate their closely affiliated universities in Darmstadt, Frankfurt, Mainz, Jena, Bochum, and Cologne on their selection as Universities of Excellence. The locations were recently announced as part of the federal and state governments’ Strategy for Excellence. This funding, which will be provided through the most significant federal-state program from 2027 onwards, sends a strong signal…

A new landmark on the GSI/FAIR campus — Artwork „Entschleunigtes Teilchen“ by Atelier Thomas Stricker installed
A copper objects stands before the blue sky.
The GSI/FAIR campus has gained a new landmark: an eight-meter-tall copper column with an organically shaped, polished-metal body in its upper third—this is the artwork “Entschleunigtes Teilchen — the FCC meteor” by Atelier Thomas Stricker. The piece emerged as the winner of the art-in-architecture competition for the FAIR Control Center (FCC) and was recently installed in front of the building.

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...
