Aerogel with index of refraction around 1.03 has been studied as Cherenkov radiator in a test at CERN PS using a π− and a mixed π+/p beam of momenta between 6 and Full-size image (<1 K). The Cherenkov photons were detected by means of four large HPD tubes designed and constructed at CERN. Results on the photoelectron yield, the Cherenkov angle and its resolution, and the π/p separation are obtained. The performances measured demonstrate that a RICH with aerogel is a viable detector for experiments with high multiplicity of particles in the final state.
