N2 - An ungated GEM-based TPC with continuous read-out is considered as the central tracker of the PANDA experiment. Particles from up to 2 · 10 7 p̄p annih./s have to be tracked over a wide momentum range (0.1-8 GeV/c). Simulations demonstrate a space charge accumulation of up to 55fC/cm3, leading to correctable track distortions of up to 6 mm. Ion backflow studies in triple-GEM structures have been performed. A spatial resolution of down to 140 μm has been achieved with a GEM-TPC test chamber, operated with an Ar/CO2 gas mixture and without magnetic field, recording the signals of cosmic muons.
