The P̅ANDA experiment, currently under construction at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, addresses fundamental questions in hadron and nuclear physics via interactions of antiprotons with nucleus / nuclei. The High Energy Storage Ring will provide an antiproton beam with a momentum range of 1.5 – 15 GeV/c and an average collision rate on the fixed target of 20 MHz is envisaged.

The barrel-shaped scintillator tile hodoscope, covering the central region of the detector, will be one of the key components to determine the time origin of the tracks and provides particle identification for slow particles below 700 MeV/c. To achieve a time resolution < 100 ps plastic scintillator tiles with minimum material budget read out by Silicon Photomultiplier (SiPM) have been selected.
In this presentation the performance of the particle identification and event separation based on the barrel scintillator tile hodoscope will be discussed.
