DOIAbstract
International audienceCOMPASS RICH-1 is a large size gaseous Imaging Cherenkov Detector providinghadron identification in the range from 3 to 55 GeV/c, in the wide acceptance spectrometer of theCOMPASS Experiment at CERN SPS.It uses a 3m long C4F10 radiator, a 21m2 large VUV mirror surface and two kinds of photondetectors: MAPMTs and MWPCs with CsI photocathodes, covering a total of 5.5m2. It is inoperation since 2002 and its performance increased thanks to progressive optimization and to amajor upgrade of its photon detection system, implemented in 2006; a new upgrade is foreseen for2016, with the use of MPGD-based photon detectors.The main characteristics of COMPASS RICH-1 components are described and the most criticalaspects related to t...
