FARICH construction optimization for the Super C-Tau Factory

The FARICH (Focusing Aerogel RICH) technique was suggested as the baseline option of the particle identification system for the Super C-Tau Factory project in Russia. In previous works, it was demonstrated that the FARICH system conceptual design is able to provide excellent \mu/\pi-separation up to a momentum of 1.5 GeV/c as well as \pi/K-separation up to 6 GeV/c. However, there are several disadvantages of this concept exist. One of them is the impossibility of providing \mu/\pi-separation below a momentum of 0.4 GeV/c. Another disadvantage is the rather large number of readout electronics channels with high power consumption (up to 100 kW), which will dissipate inside the detector. We consider, with the help of the GEANT4 simulation, the optimized construction of the FARICH system which provides \mu/\pi-separation from 0.1 to 1.5 GeV/c.
