The BMBF collaborative research center ErUM-FSP APPA comprises the German university groups who have set out to perform scientific research at the future international accelerator complex FAIR under the umbrella of APPA (Atomic, Plasma Physics and Applications). The FAIR installations are currently under construction at the site of the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany. APPA is one of the four research pillars of FAIR comprising the international research collaborations BIOMAT, FLAIR, HED@FAIR, and SPARC who focus on investigations of (anti)matter under extreme conditions (strong fields, high densities, high pressures, and high temperatures).

The ErUM-FSP APP research center pursues coordinated research projects in the area of accelerator based experiments with heavy ions at the future FAIR-installation. Central issues are:

• Further development of the the experimental infrastructure, in particular, research and development for enhancing the scientific capabilities of the existing installations and of the future accelerator and detector systems including the respective base technologies.
• Set-up of the APPA experiments of the modules 0-3 of the modularized start version of FAIR.
• Realization of the APPA research program during the current FAIR Phase-0.

Spokesperson of the Collaborative Research Center is Stefan Schippers from the Justus-Liebig-University Giessen.
