The status of the FOPI GEM-TPC * a precursor prototype for the PANDA-TPC — •Bernd Voss — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany

In 2007 the construction and building of a medium volume (Ø300mm x 650mm) Time Projection Chamber (TPC) based on Gaseous Electron Multipliers (GEM) as amplification stages has been started. The detector is foreseen to be integrated in several experiments e.g. at ELSA/Bonn as well as at FOPI/GSI. It serves as a precursor prototype for an even larger TPC (Ø840mm x 1500mm) to be incorporated in PANDA/FAIR as a central tracking device which will be built in the frame-work of a joint venture project of twelve institutions in Europe. The general design of the detector as well the current status of assembly and testing will be presented.
