Popis: International audience; COMPASS 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 the C4F10 radiator gas system, to the mirrors and their alignment, as well asthe performance of the photon detectors are presented and discussed. The response of the MWPCsand the observed evolution of the effective quantum efficiency of the CsI photocathodes is analyzed.The properties and performance of the MAPMTs with individual fused lens telescopes arepresented together with the readout characteristics. The PID performance of COMPASS RICH-1is discussed and the future upgrade program is mentioned.
