Charged particle identification for a wide momentum range is an essential task for the PANDA experiment at the future Facility for Antiproton and Ion Research (FAIR) at GSI, Darmstadt. Hadronic particle identification in the barrel region of PANDA will be performed by a DIRC (Detection of Internally Reflected Cherenkov light) counter. The design of this detector is based on the successful BABAR DIRC and has a number of key improvements, such as focusing optics, compact expansion volume, and fast timing. A detailed simulation was developed to optimize the Barrel DIRC design in terms of performance and cost.
A fast reconstruction procedure, based on the look-up tables, was used to determine the single photon Cherenkov angle resolution and photon yield. This contribution describes the procedure and presents a quantitative comparison of the performance of several design options.
