Technical design of the PANDA Disc DIRC Detector — •Erik Etzelmüller, Klim Biguenko, Michael Düren, Klaus Föhl, Avetik Hayrapetyan, Benno Kröck, Oliver Merle, and Julian Rieke for the PANDA collaboration — Jusust-Liebig-Universität, Gießen

The physics program of the PANDA detector at the future FAIR facility at GSI requires excellent particle identification. In the forward angular region between 5 and 22 degrees, this will be achieved by a DISC DIRC detector that detects internally reflected Cherenkov light in order to separate pions, kaons and other hadrons. It will be the first time that a Disc-DIRC is used in a high performance 4π detector. Technical challenges such as radiation hardness of used materials and sensors, the presence of a strong magnetic field and limited space for mechanics which arise from constraints of the PANDA environment, had to be overcome in the detector design. The actual detector design and solutions to the formerly mentioned challenges will be presented and discussed.
