PANDA DIRC Simulation and Reconstruction — Klaus Götzen1, Maria Patsyuk1,2, Klaus Peters1,2, Carsten Schwarz1, Jochen Schwiening1, and •Marko Zühlsdorf1,2 — 1GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — 2Goethe-Universität, Frankfurt
At the future facility for anti-proton and ion research (FAIR) at GSI, Darmstadt the PANDA experiment will study the physics of strong interactions. A dedicated system is required which provides excellent particle identification at a large angular and momentum range. A ring imaging Cherenkov detector based on the BABAR DIRC (Detection of Internally Reflected Cherenkov Light) will be used in the barrel region around the main interaction point. Long rectangular bars with a cross section of 17 mm × 32 mm, made from synthetic fused silica, serve as radiators and light guides.
An alternative design based on wide fused silica plates (≈ 160 mm) offers potential cost savings compared to bars. We will present a study of the performance of this design using Geant4 simulation and a fast reconstruction algorithm to determine the single photon Cherenkov angle resolution and the light yield.
