PANDA DIRC simulation and reconstruction — Carsten Schwarz1, Dipanwita Dutta1,2, Klaus Goetzen1, •Maria Patsyuk1, Klaus Peters1, and Jochen Schwiening1 — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH — 2Present address: Nuclear Physics Division, Bhabha Atomic Research Centre, Mumbai 400085, India
The PANDA experiment at the future facility for anti-proton and ion research (FAIR) at GSI, Darmstadt, aims at studying the strong interaction by precision spectroscopy. A detector system with excellent particle identification properties over a large range of solid angle and momentum is therefore mandatory. Charged hadron identification in the barrel region will be performed by a compact ring imaging Cherenkov detector based on the DIRC (Detection of Internally Reflected Cherenkov light) principle. The current design of the PANDA barrel DIRC is based on the BABAR DIRC with several important improvements, such as focusing optics and fast photon timing. We present details of the simulation of the Barrel DIRC in Geant and a study of the detector performance using a fast reconstruction algorithm to determine the single photon Cherenkov angle resolution and photon yield for several design options.
