Abstract
The extended experimental physics program accessible with the proposed Electron-Ion Collider (EIC) strongly demands for excellent particle identification (PID) of the final state hadrons. In this context two Ring Imaging Cherenkov (RICH) detectors are under development within the EIC PID consortium (EIC-eRD14 Collaboration) explicitly formed to investigate and develop PID detectors for EIC. We present the current status of development of the two RICHes: a modular RICH detector which consists of an aerogel radiator, a Fresnel lens, a mirrored box, and pixelated photon sensor; a dual-radiator RICH, consisting of an aerogel radiator and C2F6 gas in a mirror-focused configuration.
