The DIRC acronym for Detection of Internally Re ected Cherenkov light is a new type of Cherenkov ring imaging detector based on total internal re ection that is used for the rst time in the BaBar detector at PEP-II ring of SLAC. The Cherenkov radiators are long rectangular bars made of synthetic fused silica. The photon detector is a water tank equipped with an array of 10,752 conventional photomultipliers. The rst year operational experience in the BaBar detector is presented using cosmic data
