Abstract
Abstract
Super τ-Charm facility (STCF) is a future electron-positron collider operating in the
τ-Charm energy region with the aim of studying hadron structure and spectroscopy. The
baseline design of the STCF barrel particle identification (PID) detector, which covers momentum
up to 2 GeV/c, is provided by a Ring Imaging Cherenkov Counter (RICH). The RICH features an
approximately focusing design with liquid perfluorohexane sealed in a quartz container as the
radiator and a hybrid combination of CsI-coated THGEMs and Micromegas as the photo-electron
detector. A 16×16 cm2 prototype with a quartz radiator has been built and tested at
DESY and stably operated with an effective gain of 105. In this paper, the design,
performance, and reconstruction algorithm of RICH detectors are discussed.
