Abstract: The method of improvement of Cherenkov angle resolution in RICH detectors using ‘focusing’ aerogel radiators (FARICH) is under investigation. The ‘focusing’ three-layer aerogel radiator was investigated using a digital radiographic device. The Monte Carlo calculations of velocity resolution based on measured variations of the refractive index in aerogel tile are presented. With the observed variations, π- and K-mesons can be separated up to 8.4 GeV/c , π- and μ-mesons can be separated up to View the MathML source. We studied the use of sodium fluoride radiator in a RICH detector. NaF radiator extends the working momentum region for the π/K identification down to 0.6 GeV/c. It has been shown that a RICH detector with NaF radiator can achieve a competitive velocity resolution up to 5 GeV/c as compared to single-layer aerogel RICH.
