FAIR – future accelerator facility

In the coming years the new international accelerator facility FAIR, one of the largest research projects worldwide, will be built at GSI. At FAIR an unprecedented variety of experiments will be possible. Scientists from all over 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.


An international facility for research with ions

FAIR will provide particle beams with unprecedented intensity and quality. At its heart is a ring facility with a circumference of of 1100 meters. A system of cooler-storage rings for effective beam cooling at high energies and various experimental halls will be connected to the facility. The existing GSI accelerators serve as a pre-accelerators. In October 2010 nine countries in Wiesbaden have signed the international agreement on the joint construction of FAIR in Darmstadt.

To realise FAIR a new company, the FAIR GmbH, was founded.
