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.

Innovative technology and immense amounts of data —Open Data Center Day at the Green IT Cube of GSI/FAIR
People stand in front of a gray, cubic building.
For the fourth time, GSI/FAIR opened their doors to the high-performance data center Green IT Cube on the occasion of Open Data Center Day (TdoRZ). Under the slogan “Where does the internet actually live?!”, 56 participants took the opportunity to learn about the data center’s highly sustainable and energy-efficient technology and its scientific applications during guided tours.

Millions in funding for ultra-precise mass measurements of heavy, highly charged ions: Dr. Rima Schüssler heads a Young Investigator Group
Dr. Rima Schüssler at the setup: Preparing for high-precision mass measurements.
Since this year, Dr. Rima Schüssler has been leading a new Helmholtz Investigator Group (HIG) at the Helmholtz Institute Jena (HI Jena), an institute of the GSI Helmholtzzentrum für Schwerionenforschung located on the campus of Friedrich Schiller University in Jena. The team will perform high-precisison mass measurements on heavy, highly charged ions (HCIs) with the goal of testing quantum electrodynamics (QED)—and thus the Standard Model of particle physics—in strong fields with unprecedented…

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...
