The Forward Ring Imaging Cherenkov detector covers both end-cap regions of the DELPHI experiment at LEP in the polar angel 15[degree] < [theta] < 35[degree] and 145[degree] < [theta] < 165[degree]. The detector combines a layer of liquid C[sub 6]F[sub 14] and a volume of gaseous C[sub 4]F[sub 10] into a single assembly. Ultraviolet photons from both radiators are converted in a single plane of photosensitive Time Projection Chambers. Identification of charged particles is provided for momenta up to 40 GeV/c. The design of the detector is briefly described. The detector is now fully installed in DELPHI and has participated in the 1993 data taking. The overall performance will be presented together with the expectations from Monte Carlo simulations. Results close to design values are obtained.
