Measurement of the spatial and energy-loss resolution with a prototype Straw Tube Tracker (STT) for the PANDA experiment — •Alexandros Apostolou1,2, Johan Messchendorp1, James Ritman2, and Peter Wintz2 for the PANDA collaboration — 1KVI-CART, University of Groningen — 2Forschungszentrum Juelich, Juelich
The PANDA experiment is one of the pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. The PANDA physics program is focused on answering fundamental questions related to Quantum Chromodynamics (QCD), mostly in the non-perturbative energy regime, using antiproton collisions on proton and nuclear targets. The central Straw Tube Tracker (STT) will be the main tracking detector of the PANDA target spectrometer. The STT will reconstruct tracks induced by charged particles (with a spatial resolution of ≃ 150 µm transversal) and measure the corresponding particle momenta and specific energy-losses for particle identification (PID) with an energy resolution better than 10%. The PID information from the STT is especially needed to separate protons, kaons and pions in the momentum region below 1 GeV/c. In this work, the results obtained so far with a prototype STT using the proton beam at COSY in the momentum range from 0.5 to 3.0 GeV/c are summarised and discussed.
