Abstract

The main goal of the NA62 experiment is the measurement of the K⁺ → π⁺νν̅ branching ratio with a precision better than 10%. One of the key element of NA62 is the Ring Imaging CHerenkov detector (RICH). It will identify pions and muons in the momentum range between 15 and 35 GeV/c, with a muon rejection factor better than 10^-2. The RICH will also measure the particle arrival time with a precision better than 100 ps to disentangle accidental time associations of beam particles with pions and will provide the reference time and a fast signal for the NA62 trigger system. We present the final design of the detector and the status of the construction. Finally, we recall the results of the beam tests of the RICH prototype.
