Abstract

A novel technique for particle identification of relativistic heavy ions has been developed utilizing a Heavy-Ion Ring Imaging Cherenkov detector (HIRICH) for velocity measurement. The HIRICH is characterized by a thin liquid or solid state radiator, a proximity focusing geometry and a fast gaseous photon detector with CsI photon converter. A velocity resolution of Δβ/β = 8×10-4 (fwhm) has been measured for Ru44+ particles of β≈0.85. The detector design and the performance in heavy-ion reaction studies at the GSI-Darmstadt are presented.
