Abstract :
A new approach to study the performance characteristics of the HERA-B RICH using momenta reconstructed with RICH track direction measurements is presented. The particle identification performance is found to meet design specifications: electron–pion separation for momenta up to 15 GeV/c, pion–kaon separation to 54 GeV/c. The normalized photo-electron yield is found to be 42±5 cm−1 rad−2 and the single-photon angular resolution is better than 0.7 mrad.
