Identification of high p⊥ particles with the STAR-RICH detector

Abstract The STAR-RICH detector extends the particle identification capabilities of the STAR experiment for charged hadrons at mid-rapidity. This detector represents the first use of a proximity-focusing CsI-based RICH detector in a collider experiment. It provides identification of pions and kaons up to 3 GeV /c and protons up to 5 GeV /c . The characteristics and performance of the device in the inaugural RHIC run are described.
