FAIR – Facility for Antiproton and Ion Research

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 antiprotons and ions

FAIR will provide antiproton and ion beams with unprecedented intensity and quality. In the final construction FAIR consists of eight ring colliders with up to 1,100 meters in circumference, two linear accelerators and about 3.5 kilometers beam control tubes. 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.
