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...
