The DIRC detectors of the P¯ANDA experiment at FAIR

The P¯ANDA experiment at the future Facility for Anti-proton and Ion Research (FAIR) aims at studying the strong interaction with antiprotons in the 1–15 GeV/c   range. For the charged particle identification, in particular of kaons, one foresees two DIRC detectors. These will be located in the target spectrometer section of P¯ANDA. A barrel shape DIRC with bar radiators will cover the central region, and a disc DIRC will be located in the forward endcap part. For the latter, two readout concepts are investigated: measuring the photon time-of-propagation in a multi-wavelength band disc DIRC, or measuring angles in a focussing lightguide dispersion-correcting disc DIRC.
