Abstract
Lately aerogel samples of refractive index as high as 1.13 were synthesized in Novosibirsk. Light scattering length for some samples approaches 12 cm.We performed a Geant4 simulation for a FARICH with aerogel of 1.10 index of refraction. Two photodetector options were considered: Burle MCP PMT and a novel photodetector—Hamamatsu MPPC. It is shown that FARICH with MPPC photodetector is able to separate at 3σ3σ level pions and kaons up to 8 GeV/c, muons and pions up to 1.5 GeV/c momentum.The project of Forward RICH for SuperB factory based on focusing aerogel radiator is presented.It is demonstrated that using a FARICH detector for the momentum measurement the momentum precision can be significantly improved.
