The LHCb experiment is a single forward arm spectrometer at the LHC at CERN. Particle identification (pion, kaon
and proton discrimination) is a crucial requirement to meet the physics goals of the experiment. This is
provided by two Ring Imaging Cherenkov (RICH) detectors providing particle identification coverage between 1 and
100 GeV/c.
After a brief description of the LHCb experiment and RICH detectors, the results from the latest beam test using
the final detector components and readout system will be given and the anticipated particle identification
performance of the RICH detectors from Monte Carlo simulations will be presented. Finally a technique to
calibrate the particle identification performance of the RICH system with data using $D^{*}$ decays will be
described.
