GSI Helmholtzzentrum für Schwerionenforschung

GSI Helmholtzzentrum für Schwerionenforschung operates a unique large-scale 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.

Dr. Andreas Mooser received the GSI doctoral candidate award. He was awarded for his doctoral research on high-precision measurement of magnetic moment of proton. The award, which is presented every year, is endowed with 1000 Euro and is funded by Pfeiffer Vacuum. The award was presented by GSI scientific director, Professor Karlheinz Langanke, and Dr. Ulrich von Hülsen, a member of Pfeiffer Vacuum GmbH management. Guest of honor and speaker was ESA General Director Johann-Dietrich Wörner.

Johannes Ullmann received the Giersch Excellence Grant for his works on the determination of the hyperfine splitting energy of the ground state of hydrogen and lithium like Bismuth by laser spectroscopy. The Experiment was conducted at the experimental storage ring of the GSI Helmholtz Center for Heavy Ion Research in Darmstadt and allows a precise test of quantum electrodynamics in extreme electric and magnetic fields.

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...
