The NA62 experiment at CERN aims to measure the ultra-rare decay K+ -> pi+ v (v) over bar with a 10% accuracy: the main background, K(+) -> mu(+) v, is suppressed using kinematical cuts and exploiting the different stopping power of pi(+) and mu(+). A further 0.5% suppression will be provided by a RICH detector, in a momentum range between 15 and 35 GeV/c. In this paper the design parameters of a RICH detector that fulfills the NA62 experiment requirements will be described, as well as results from two different beam tests.
