STEFAN SCHIPPERS1 UND THOMAS STÖHLKER2,3 FOR THE APPA-COLLABORATIONS

1I. Physikalisches Institut, Justus-Liebig-Universität Gießen2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt3Helmholtz-Institut Jena APPA (Atomic and Plasma Physics and Applications) next to

CBM, NUSTAR and PANDA is one of the four research pillars of

FAIR. The following research collaborations are acting under the

umbrella of APPA:

• BIOMAT (biophysics and materials science),

• FLAIR (physics with low-energy antiprotons),

• HED@FAIR (plasma physics),

• SPARC (atomic physics).

The common research topic is the exploration of the building blocks

and of the phenomena of matter under extreme conditions

(high fields, densities, pressures and temperatures).

The APPA R&D research collaboration of German university groups pursues coordinated research projects in the area of accelerator based experimentswith heavy ions at the future FAIR installation. Central issues are: • Further development of 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.
