New developments of the PANDA Disc DIRC detector

The DIRC principle (Detection of Internally Reflected Cherenkov light) allows a very compact approach for particle identification detectors. The PANDA detector at the future FAIR facility at GSI will use a Barrel-DIRC for the central region and a Disc DIRC for the forward angular region between 5◦ and 22◦ . It will be the first time that a Disc DIRC is used in a high performance 4π detector. To achieve this aim, different designs and technologies have been evaluated and tested. This article will focus on the mechanical design and integration of the Disc DIRC with respect to the PANDA environment.
