SCIENCE POP-UP by GSI/FAIR becomes a permanent place to go for science enthusiasts in the inner city of Darmstadt
Exciting innovations: Upgrade for the accelerator game.
What started as a temporary project will now become a permanent inner-city institution in Darmstadt for the next two years: The SCIENCE POP-UP project, an interactive hands-on exhibition for science enthusiasts of all ages, remains at its location at Ernst-Ludwig-Straße 22 in the long term. This establishes the successful initiative of the GSI Helmholtzzentrum für Schwerionenforschung and the international accelerator center FAIR as a long-term point of contact for anyone interested in ...

From Excavation to Giant: FAIR Construction Site in Time-Lapse
FAIR construction in time-lapse
When thousands of tons of concrete and steel turn into high technology: the new long-term drone-lapse shows seven years of FAIR construction progress—condensed into 1.5 minutes. From the excavators in 2018 to the completed buildings and installation of technical equipment in 2025: floors rise rapidly, and raw structures transform into high-tech laboratories.

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...
