Progress in the simulation of PANDA barrel DIRC

An excellent particle identification (PID) of hadrons and leptons over a large range of solid angle and momenta is an essential requirement for the precision measurement aims in PANDA experiment at FAIR, GSI [1]. For charged hadron identification in the barrel region of the PANDA detector, a compact imaging Cherenkov detector following the DIRC (Detection of Internally Reflected Cherenkov light) principle is foreseen [2]. The simulation, realistic digitization and reliable reconstruction of the Cherenkov angle is mandatory for the performance study of the full PANDA detector system. In this contribution, we will discuss the progress in the simulation of the barrel DIRC in the PandaRoot framework.
