The recent announcement of the construction of an Electron Ion Collider (EIC) at Brookhaven National Laboratory by the U.S. Department of Energy makes the reality of a long-sought experimental effort to explore the structure and properties of proton and nuclei in unprecedented precision and broad kinematic coverage. Particle identification (PID) of the final state hadrons is a key requirement for EIC. In order to meet the challenge of the confined volume of the electron endcap in EIC experiments, a compact, projective, and modular ring imaging Cherenkov (mRICH) detector is proposed for $K/\pi$ separation from $3$ up to $10$~GeV/c. At the same time, the mRICH design has a significant potential for $e/\pi$ identification providing an important capability supplementing the electromagnetic calorimeters and other possible $e/\pi$ PID systems. The mRICH detector consists of an aerogel radiator block, a Fresnel lens, a mirror-wall and a photosensor plane. The first prototype of this detector design was successfully tested at Fermi National Accelerator Laboratory in April 2016 for verifying the detector working principles. This talk will highlight the recent advances and the beam test results of the second mRICH prototype in 2018. A future plan for the mRICH development will also be discussed in this presentation.
