    "abstract": "Particle identification at high rates is an important challenge for many\ncurrent and future high-energy physics experiments. The upgrade of the COMPASS\nRICH-1 detector requires a new technique for Cherenkov photon detection at\ncount rates of several $10^6$ per channel in the central detector region, and a\nread-out system allowing for trigger rates of up to 100 kHz. To cope with these\nrequirements, the photon detectors in the central region have been replaced\nwith the detection system described in this paper. In the peripheral regions,\nthe existing multi-wire proportional chambers with CsI photocathode are now\nread out via a new system employing APV pre-amplifiers and flash ADC chips. The\nnew detection system consists of multi-anode photomultiplier tubes (MAPMT) and\nfast read-out electronics based on the MAD4 discriminator and the F1-TDC chip.\nThe RICH-1 is in operation in its upgraded version for the 2006 CERN SPS run.\nWe present the photon detection design, constructive aspects and the first\nCherenkov light in the detector.",
