Abstract
The PANDA spectrometer will be built at the FAIR facility at Darmstadt (Ger- many) to perform accurate tests of the strong interaction through ¯ pp andannihilation studies. The charged particle tracking at PANDA will be done using both solid state and gaseous detectors. Among the latter, two straw tube detector systems will be built (1). The cylindrical, central straw tube tracker features a high spatial and momentum resolu- tion for a wide range of particle momenta from about 8 GeV/c down to a few 100 MeV/c, together with particle identification in the momentum region below about 1 GeV/c by measuring the specific energy-loss. A new technique, based on self-supporting straw double layers with intrinsic wire tension developed for the COSY-TOF straw tracker (2), has been adopted for the PANDA trackers. The development of the readout electronics for the straw tubes is ongoing. Prototypes have been produced and used to instrument straw tube modules that have been tested with cosmic rays and proton beams. Design issues of the PANDA straw tubes, together with the results of the prototype tests are presented. The PANDA experiment (3) is one of four experiments planned for the future Facility for Antiproton and Ion Research (FAIR) (4) in Darmstadt, Germany. The scientific program of the PANDA Collaboration is oriented towards precise studies of strong interaction in the QCD transi- tion region between asymptotically free quarks and hadronic matter. The maximum available center of mass total energy in the PANDA experiment ( √ s= 5.46 GeV/c 2 ) will allow hadronic structures involving the charm quark degrees of freedom to be investigated. The PANDA detector will be in- stalled around the internal target of the High Energy Storage Ring (HESR), which will accumulate, accelerate and cool up to 10 11 antiprotons. In the experiment, the annihilation of antiprotons with

Summary
The PANDA experiment [3] is one of four experiments planned for the future Facility for Antiproton and Ion Research (FAIR) [4] in Darmstadt, Germany. The PANDA detector will be installed around the internal target of the High Energy Storage Ring (HESR), which will accumulate, accelerate and cool up to 1011 antiprotons. In the TS are foreseen: a silicon Micro Vertex Detector (MVD) [6] which encloses the interaction point, a Straw Tube Tracker (STT) surrounding the MVD and the 3 layers of planar chambers based on GEM foils at forward angles.
