DESCRIPTION:Speakers: Alexander Barnyakov (Budker Institute of Nuclear Phy
 sics)\nThe Super Charm-Tau (SCT) Factory project is a future electron-posi
 tron colliding beam experiment with unprecedented high luminosity $10^{35}
 $cm$^{-2}$s$^{-1}$ at the interaction energy range from 3 to 7 GeV. The ph
 ysics program of the experiment is aimed to search the phenomena beyond th
 e standard model and its precise  calibration in this energy range. The ma
 in features of the SCT Factory project are presented. To perform the broad
  physics program at the ultimately high beam intensity the high performanc
 e universal detector is proposed. One of the proposed detector subsystems 
 is the PID system based on Focusing Aerogel RICH (FARICH) technique. The p
 roposed FARICH scheme combined with abilities of tracking system will prov
 ide the excellent $\\pi/K$-separation for the whole operation momentum ran
 ge and $\\mu/\\pi$-separation up to momentum of 1.5 GeV/c. The idea of FAR
 ICH detector based on dual  aerogel radiator (focusing aerogel tile with m
 aximal refractive index 1.05 and high optical density aerogel with refract
 ive index of 1.12) is described. Results of GEANT4 simulation and beam tes
 t results are in good agreement. PID capabilities of this approach is demo
 nstrated with help of numerical simulation. In 2023 two multilayer focusin
 g aerogel samples with overal sizes 230$\\times$230$\\times$35$~$mm were p
 roduced in Novosibirsk for the first time all over the world. The results 
 of the first beam tests of these aerogel samples and comparison with simul
 ation are presented. Conceptual design and some technical issues of the PI
 D system based on FARICH technique are discussed as well.\n\nhttps://indic
