Abstract :
The main goal of the NA62 experiment at SPS CERN is to measure the branching fraction of the ultra-rare kaon decay K+ → π+νν̅ with ~10% precision. RICH is a crucial detector for background suppression and particle indentification. RICH will provide muon/pion separation at the ~0.5% level in the momentum range between 15 and 35 GeV/c, unique time resolution (~100 ps) and a fast signal for the trigger system. This paper describes the main features of the RICH detector, results of the test beam and the construction status.
