    "abstract": "The COMPASS experiment at the SPS accelerator at CERN uses a large scale Ring\nImaging CHerenkov detector (RICH) to identify pions, kaons and protons in a\nwide momentum range. For the data taking in 2006, the COMPASS RICH has been\nupgraded in the central photon detection area (25% of the surface) with a new\ntechnology to detect Cherenkov photons at very high count rates of several 10^6\nper second and channel and a new dead-time free read-out system, which allows\ntrigger rates up to 100 kHz. The Cherenkov photons are detected by an array of\n576 visible and ultra-violet sensitive multi-anode photomultipliers with 16\nchannels each. The upgraded detector showed an excellent performance during the\n2006 data taking.",
