FARICH Construction Optimization for the Super C-Tau Factory

The FARICH(Focusing Aerogel RICH)technique was suggested as the baseline option of the particle identific-ation system for the Super C-Tau Factory project in Russia.In previous works,it was demonstrated that the FARICH sys-tem conceptual design is able to provide excellent μ/π-separation up to a momentum of 1.5 GeV/c as well as π/K-separation up to 6 GeV/c.However,there are several disadvantages of this concept exist.One of them is the impossibility of provid-ing μ/π-separation below a momentum of 0.4 GeV/c.Another disadvantage is the rather large number of readout electron-ics 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 μ/π-separation from 0.1 to 1.5 GeV/c.
