Abstract :
Cooled antiproton beams of unprecedented intensities in the momentum range of 1.5–15 GeV/c will be used for the P ¯ ANDA experiment at FAIR to perform high precision experiments in the charmed quark sector. The proposed P ¯ ANDA detector is a 4 π internal target spectrometer at the HESR allowing the detection and identification of neutral and charged particles generated within the total energy range of the antiproton annihilation products. The detector is divided in a forward spectrometer and a target spectrometer. The charged particle identification in the latter is performed by ring imaging Cherenkov counters employing the DIRC principle.
