Test of prototypes of the PANDA Disc DIRC — •Peter Koch, Michael Düren, Klaus Föhl, Avetik Hayrapetian, Kristof Kreutzfeldt, Benno Kröck, Oliver Merle, Michael Sporleder, and Marko Zühlsdorf — II. Physikalisches Institut, Universität Giessen, Germany

The Panda Disc DIRC is a detector for particle identification in the forward direction of the PANDA experiment at FAIR. It uses internally reflected Cherenkov light that is emitted by a charged particle crossing a transparent disc. During 2010, several test beam experiments at DESY, CERN and Jülich have been done using glass and acrylic glass radiators and focusing elements to map the Cherenkov cone onto position sensitive photon detectors. Several fast avalanche photo diodes (APDs), multichannel plate photomultipliers (MCP-PMTs) and the new digital silicon photomultipliers (dSiPMs) from Philips have been tested. First results will be presented.
