The central tracker of the P¯ANDA detector

One of the main components of the new international research facility called FAIR (Facility for Antiproton and Ion Research) [Facility for Antiproton and Ion Research. http://www.gsi.de/fair/index e.html], to be constructed in Darmstadt, Germany, is a storage ring for phase-space-cooled antiprotons—High Energy Storage Ring (HESR). The P¯ANDA (P¯ (antiproton) ANnihilation in DArmstadt) [Strong Interaction Studies with Antiprotons, Technical Progress Report for P¯ANDA. http://www-panda.gsi.de/archive/public/panda_tpr.pdf] experiment is a state-of-the-art detector at HESR covering almost the complete solid angle with an internal target. This experiment will investigate QCD in the charmonium mass region.The central tracker is the essential part of the P¯ANDA detector, providing information about primary and secondary decay vertices, momenta of charged particles and particle identification.
