Mourning Hans Gutbrod
Mourning Professor Dr. Hans Gutbrod
GSI and FAIR mourn the loss of an excellent scientist and pioneer of relativistic heavy ion physics. Professor Dr. Hans Gutbrod passed away on March 3, 2025, at the age of 82 years. After his dissertation under the supervision of Rudolf Bock in 1970 Hans Gutbrod continued his research on heavy ion physics at low energies in Heidelberg and Rochester. Hans Gutbrod shaped the beginnings of the relativistic heavy ion physics at the Lawrence Berkeley National Laboratory. He collaborated with Arthur…

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...
