Simulation and reconstruction for the PANDA Barrel DIRC — Klaus Götzen1, •Maria Patsyuk1,2, Klaus Peters1,2, Carsten Schwarz1, Jochen Schwiening1, and Marko Zühlsdorf1,2 — 1GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — 2Goethe Universität Frankfurt
The PANDA experiment at the new Facility for Antiproton and Ion Research in Europe (FAIR) at GSI, Darmstadt, will study fundamental questions of hadron physics and QCD. Efficient Particle Identification (PID) for a wide momentum range and the full solid angle is required for reconstructing the various physics channels of the PANDA program. Hadronic PID in the barrel region of the detector will be provided by a DIRC (Detection of Internally Reflected Cherenkov light) counter. The design is based on the successful BABAR DIRC with important improvements, such as focusing optics and fast photon timing.
A detailed detector simulation of the Barrel DIRC, including a number of design options, was performed using Geant. A reconstruction algorithm was developed to quantify the performance in terms of single photon Cherenkov angle resolution and photon yield. Simulation and performance of the design options will be discussed in this contribution.
