摘要：
The upgrade of the Jefferson Lab accelerator to 12 GeV electron beam energy, combined with that of the CEBAF Large Acceptance Spectrometer (CLAS12) located in Hall B, will provide the unique combination of wide kinematical coverage, high beam intensity (luminosity), high energy, high polarization, and advanced detection capabilities required to study Quantum Chromodynamics (QCD) in greater details. A Ring Imaging Cherenkov (RICH) will significantly enhance CLAS12 particle identification capabilities by providing clean separation between pions, kaons and protons over momenta from 2 to 8 GeV/c. A detailed simulation of a preliminary design of the RICH detector for CLAS12 using GEANT-4 Monte-Carlo will be presented. A reconstruction algorithm based on a likelihood approach will be discussed.
