Abstract

The Barrel-Time-of-Flight detector is one of the outer layers in the multi-layer design of the P̄ANDA target spectrometer, covering a polar angle region of 22°<θlab<150°. P̄ANDA, which is being built at the FAIR facility, will use cooled antiprotons on a Hydrogen or nuclei target, to study a variety of topics in hadron physics. The detector is a scintillating tile hodoscope with an SiPM readout. A single unit consists of a 90×30×5 mm3 fast plastic scintillator tile and 3 × 3 mm2 SiPM photosensors on both ends. Four SiPMs are connected in series to overcome the limited sensor size of a single SiPM sensor and to improve the time resolution drastically (100 ps to 50 ps). While the P̄ANDA experiment is equipped with DIRC detectors for PID of faster particles, the Barrel TOF complements the setup by providing additional PID information with a π/K separation of 4 sigma up to the Cherenkov threshold.
