Through Nuclear physics, Matter and Biology
FAIR will be based upon an expansion of the GSI Helmholtz Centre for Heavy Ion Research, the details of which have been laid out in the FAIR Baseline Technical Report 2006. On October 4, 2010 the Facility for Antiproton and Ion Research in Europe limited liability company (German GmbH), abbreviated as FAIR GmbH, was founded which coordinates the construction of the new accelerators and experiments.
The construction begun in the summer of 2017. Commissioning is planned for 2025. The original budget had been estimated at 1262 million euro (2005 price level), in 2018 the German Federal Court of Auditors stated that the cost of FAIR had increased to at least 1669 million euro (2005 prices), in 2019 a further report by the Federal Court of Auditors quoted results from a review board that an additional 850 million euro (2019 prices) would be needed to finish building the facility.
FAIR science case
The four scientific pillars of FAIR are:
- Atomic, Plasma Physics and Applications – APPA,
- Compressed Baryonic Matter – CBM,
- Nuclear Structure, Astrophysics and Reactions – NUSTAR,
- antiProton ANnihilation at DArmstadt – PANDA.
Those are described on the web pages of FAIR (see and links therein).

FAIR accelerators
Beams of protons will be prepared in the proton linear accelerator, p-LINAC, while heavy ions will be prepared in the UNILAC. Both of them will be fed into the SIS18. From there they will be directed into SIS100 (and SIS300 if applicable). Protons will be used either to produce antiproton beams by directing them on a dedicated production target or directly used for experiments within APPA. These antiprotons will be captured and cooled in the Collector Ring, CR (and RESR when available) before being injected into HESR, where they will be utilised within the PANDA experiment. High energetic heavy ions will either be used directly for studies with the CBM or APPA experiments or to produce unstable ion beams. The latter will be produced in the Rare Isotope Production Target and filtered the Super-FRS, where the NUSTAR experiments will take place.
FAIR partner
Countries
Roughly 3,000 scientists from more than 50 countries are already working on the planning of the experiment and accelerator facilities. This project is realised by partners from Finland, France, Germany, India, Poland, Romania, Russia, Slovenia and Sweden that have signed an international treaty, the FAIR Convention, which formally entered into force in March 2014. The UK joined in 2013 as its first associate member. In 2018 the Czech Republic joined as an aspirant partner. Further countries, like Italy, are in negotiations.
Institutions
FAIR has also formed a strategic partnership with the Technische Universität Darmstadt, which is located in the same city as FAIR.
