Description
The Super C-$\tau$ Factory at Novosibirsk is a project of electron-positron collider with luminosity 10$^{35}$cm$^{-1}$s$^{-1}$ for experiments at energy range of $\tau$-lepton and charmonium states production. To investigate rare decayes of D-mesons or $\tau$-leptones and for search of "new Physics" the excellent particle identification system is needed. The main requirements for PID system are following: good $\pi$/K-separation in whole operational momentum range and good $\mu$/$\pi$-separation up to 1.2 GeV/c. Few options are under consideration today: FARICH (Focusing Aerogel RICH) based on 4-layer aerogel tiles and more than 1 million channels photon detection pixels, threshold ASHIPH ( Aerogel SHifter PHotomultiplier) counters with 6000 liters of aerogel of two refractive indexes and TOF approach with time resolution better than 30 ps. All options are described. Results of simulation and some results of prototypes tests are presented.
