 note = {RI-RICH, a ring-imaging Cherenkov counter for radioactive ions, has been developed to measure the velocity of the ions at intermediate energies. Our RI-RICH system consists of six multi-anode photomultiplier tubes covered with 360-nm bandpass filters and a radiator made of quartz or BK7. For the primary 132Xe beam with a velocity of , a velocity resolution of  (one standard deviation ) and a detection efficiency of more than 99.99% were achieved. For the secondary beams with  and , we successfully performed particle identification using the -- method. The velocity resolutions of RI-RICH for these nuclides were equivalent to a more than  separation for the mass number.},
