FAIR accelerator facility

Centerpiece is a superconducting ring accelerator with a circumference of 1100 meters. Additionally several storage rings and experiment sites.

GSI accelerator facility

Will be part of the FAIR accelerator facility and serve as first acceleration step.

Specifications of the FAIR accelerator facility

Highest particle intensity, highest precision, highest diversity of accelerated ions, high particle energies (correspond up to 99 percent of the speed of light), parallel operation of up to four experiments at the same time

Research at FAIR

„The universe in the laboratory“. FAIR provides new insights into the structure of matter and the evolution of the universe from the Big Bang until today. Here, it is possible to create states of matter in the laboratory that otherwise only exist in the universe e.g. in stellar explosions or in the core of planets.

Employees of GSI and FAIR

1,400 employees

Scientific users of the FAIR facility

3000 researchers from 50 countries.


The major part of the facility will be commissioned in 2022, full operation is planned for 2025.

Total cost

1,262 million Euro plus 95 million Euro site-related costs, thus overall cost frame 1,357 million Euro (price level of 2005 respectively).
