The Technical University of Applied Sciences Mittelhessen (THM) and GSI/FAIR in Darmstadt intend to collaborate more closely in the field of particle therapy. A corresponding collaboration agreement was recently signed by both partners. The goal is to improve particle therapy both for the Marburg Ion Beam Therapy Center (MIT) and centers worldwide, as well as to support translational and basic research like it is conducted at the GSI/FAIR accelerator facilities.

BASE experiment at CERN succeeds in transporting antimatter
Antimatter on the road - for the first time antiprotons were transported in by a truck.
On 24 March 2026, in a world first, a team of scientists from the BASE experiment at CERN, including GSI researchers, successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed to accumulate a cloud of antiprotons in an innovative portable cryogenic Penning trap, then disconnect it from the experimental facility, load it onto a truck and continue experiment operation after transport. This is a remarkable achievement, given that…

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...
