Abstract: Super τ-Charm facility (STCF) is a future electron-positron collider operating in theτ-Charm energy region with the aim of studying hadron structure and spectroscopy. Thebaseline design of the STCF barrel particle identification (PID) detector, which covers momentumup to 2 GeV/c, is provided by a Ring Imaging Cherenkov Counter (RICH). The RICH features anapproximately focusing design with liquid perfluorohexane sealed in a quartz container as theradiator and a hybrid combination of CsI-coated THGEMs and Micromegas as the photo-electrondetector. A 16×16 cm$^{2}$ prototype with a quartz radiator has been built and tested atDESY and stably operated with an effective gain of 10$^{5}$. In this paper, the design,performance, and reconstruction algorithm of RICH detectors are discussed.
