Fraunhofer IGD launches powerful GPU cluster
A row of black racks is mounted in a structure of green metallic beams. At the front, a sticker reacing "Baltic Brain" is placed.
With a new high-performance computing infrastructure, Fraunhofer IGD and GSI/FAIR are strengthening their collaboration in the fields of artificial intelligence and high-performance computing. The new GPU cluster combines Fraunhofer IGD’s AI expertise with the energy-efficient data center infrastructure of GSI/FAIR’s Green IT Cube and creates the technical foundation for training modern AI models for data-sovereign research and the secure handling of sensitive information.

Laser spectroscopy helps reveal hidden nuclear properties in fermium
A laser beam strikes (figuratively) a fermium isotope in the nuclide chart. The schematic measurement setup is shown in the background.
First high-precision measurements of the fermium-255 nucleus validate modern nuclear models and advance the search for superheavy elementsFor the first time, researchers have determined the shape of the actinide nucleus of fermium‑255 and measured its structure with high precision and resolution. This breakthrough, published in Physical Review Letters, supports modern theoretical models and opens new possibilities for understanding the behavior of the heaviest atomic nuclei.

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...
