An R&D program is proposed to build a Ring Imaging Cherenkov Counter (RICH) prototype, to be used for the particle identification up to the momentum of 10 GeV/c in the EIC forward region. Innovative techniques of photo-detectors and aerogel radiator will be exploited. The forward RICH requires the detection of single photons on large surfaces, with high time and space resolutions, insensitivity to magnetic fields, high quantum efficiency in the visible and close to ultraviolet wavelength region, limited and uniform radiation length over the entire detection surface, and a limited total geometrical length of the whole detector. In particular two innovative techniques will be applied to this prototype of proximity focusing RICH detector: aerogel block radiators with varying refraction index and a detector plane for Cherenkov photons assembled with silicon photomultipliers (SiPM).
