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.

Heavy-ion synchrotron SIS18 - exterior view.
An innovative computer model of a human lung is helping scientists simulate, for the first time, how a burst of radiation interacts with the organ on a cell-by-cell level. This research, carried out at the University of Surrey and the GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, could lead to more targeted treatments for cancer and reduce the damage caused by radiotherapy.

Recently, groundbreaking progress has been made for the large FAIR ring accelerator SIS 100: A section of the cryogenic part of the SIS100 was built at the STF series test facility on the GSI/FAIR campus and then tested for the first time at the required operating temperature of -269 degrees Celsius. This decisive step, the so-called string test, marks an important final milestone in the construction of large superconducting circular accelerators. It is mainly used to test the interfaces and...



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...
