The electronic readout of the PANDA Straw Tube Tracker — •Stephan Leiber, James Ritman, and Peter Wintz for the PANDA collaboration — Forschungszentrum Jülich GmbH
The PANDA experiment at FAIR will use antiproton beams with momenta between 1.5 and 15 GeV/c and proton, deuteron or nucleon targets to study pp-annihilations in the charm quark mass regime with √s = 2.3 - 5.5 GeV.
The central Straw Tube Tracker (STT) in the PANDA-spectrometer is a gas detector consisting of 4636 closed-packed, self supporting straw tubes which are arranged in six hexagonal sectors and 23 - 27 radial layers to precisely measure the particle tracks and their specific energy loss dE/dx for particle identification. The single hit resolution is about σxy = 150 µm and σz = 2 - 3 mm and the information of the particle identification (σ(dE/dx) < 10 %) is needed to separate protons, pions and kaons with momenta below 1 GeV/c.
In 2013 the construction phase of the STT started. The design including the readout system will be described and results from in-beam and cosmic ray tests will be shown.
