The Straw Tube Tracker of the PANDA experiment

The PANDA experiment will investigate many aspects of particle and nuclear physics. This will be done by using the excellent quality antiproton beam that will be provided at the HESR storage ring, under construction as a part of the FAIR facility at Darmstadt, Germany. The experimental apparatus will be a fixed target detector with a central and a forward spectrometer. The PANDA central tracker is a key element of the experiment; it will provide information about decay vertices, momenta and charged particle species emitted after antiproton annihilation. Two possibilities are presently under study for this detector. The Straw Tube Tracker option will be illustrated together with experimental results of the R&D phase.
