Description
The future $e^{-}e^{+}$ Super Charm-Tau Factory (SCTF) to be built at Novosibirsk will cover an energy range of 2 -- 6 GeV. The projected record luminosity of $10^{35}$ cm $^{-2} s^{-1}$ and the longitudinal polarization of the electrons will enable a wide range of standard model precision tests and options for the discovery of flavor violating decays beyond the standard model. A 4$\pi$ detector with excellent particle identification (PID) required with challenging $\mu / \pi$-separation in the range 0.2 -- 1.2 GeV/c. This talk focuses on two new concepts and the first tests of novel Cherenkov detectors for SCTF, a focusing aerogel RICH (FARICH) and a focusing DIRC (FDIRC). Both require single-photon detection with good coordinate and timing resolution. The prototyping for both versions already started at BINP and Giessen. The tests include various photon detectors (MCP-PMT, SIPM, MPPC). The first results using cosmic muons at the Giessen Cosmic Station are presented.
