The Facility for Antiproton and Ion Research (FAIR), is a new international accelerator facility for the research with antiprotons and ions. It entered the ESFRI roadmap in 2006 and is one of the ESFRI landmarks. It provides high-energy, high intensity primary and secondary beams of antiprotons and ions to enable forefront research into the structure and dynamics of matter under extreme conditions, thereby also providing new insights.

into the evolution of the Universe and the nucleosynthesis in stars and star explosions. In total over 50 countries are involved in the FAIR science program by contributing to the construction and to the exploitation of the FAIR detectors.
