  The STAR-RICH detector extends the particle identification capapbilities 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.
