The original budget had been estimated at 1262 million euro (2005 price level),[5] in 2018 the German Federal Court of Auditors stated that the cost of FAIR had increased to at least 1669 million euro (2005 prices),[6] 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.

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.

The latter will be produced in the Rare Isotope Production Target and filtered the Super-FRS, where the NUSTAR experiments will take place.

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.
