AB  - The PANDA experiment at the international accelerator Facility for Antiproton andIon Research in Europe (FAIR) near GSI, Darmstadt, Germany will address fundamentalquestions of hadron physics. Excellent Particle Identification (PID) over a largerange of solid angles and particle momenta will be essential to meet the objectivesof the rich physics program. Charged PID for the barrel region of the PANDA targetspectrometer will be provided by a DIRC (Detection of Internally Reflected Cherenkov light) detector.The PANDA Barrel DIRC is designed to cover the polar angle range of 22-140 degreesand separate charged pions from kaons for momenta between 0.5 GeV/c and 3.5 GeV/cwith a separation power of at least 3 standard deviations. The design is based onthe successful BABAR DIRC and the SuperB FDIRC R</td><td width="150">
AB  - D with several importantimprovements to optimize the performance for PANDA, such as a focusing lens system,fast timing, a compact fused silica prism as expansion region, and lifetime-enhanced Microchannel-Plate PMTs for photon detection.Detailed Monte-Carlo simulations were performed and two reconstruction methodwere developed to study the performance of the design.We will discuss the baseline design of the PANDA Barrel DIRC, based on narrow barsmade of synthetic fused silica and a complex multi-layer spherical lens system andpresent the result of tests of a large system prototype with a mixed hadron beam at CERN.
