Particle identification system based on Focusing Aerogel RICH (FARICH) detector is considered as an option for the future experiments at the Super Charm-Tau Factory (Russia). New samples of focusing 4-layer aerogels with maximal refractive index 1.065 were produced in 2020–2021. First beam test results with relativistic electrons demonstrate single photon resolution (SPR) of 9-10 mrad. According to simulation results, the aerogels with such SPR are able to provide mu\pi-separation at the level of more than 3 standard deviations for tracks with momentum 1.5 GeV/c.
