As there is a lot of interest in the online visits at GSI and FAIR, the popular offer will be continued: The next date is April 8 (Thursday) at 2 pm; further dates are in preparation and will be published on our homepage. The live moderated events offer a comprehensive insight into current research and the experimental facilities at GSI/FAIR and allow individual questions to be asked, which will be answered by the presenters. Also included is an exclusive view at the mega construction site for…

Also in this year GSI and FAIR participated in the International Masterclasses for particle physics. Within the framework of an ALICE Masterclass, 30 students were able to get an insight into the daily work and data analysis in particle physics. ALICE is one of the four large experiments at the accelerator LHC located at the European research center CERN in Geneva. ALICE investigates in particular collisions of nuclei of heavy lead atoms. Due to the Corona pandemic, the event was held in a…



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...
