    One quarter of the Forward Ring Imaging Cherenkov (Forward RICH) detector has been installed and operated in the DELPHI experiment. The detector covers the forward-backward regions (15 degrees < theta <35 degrees ). Two radiator systems are used for particle identification in the momentum range up to 40 GeV/c, i.e., a liquid perfluorohexane and perfluorobutane gas. UV-photons with wavelengths from approximately 170 nm to approximately 200 nm (7.3-6.2 eV) are detected with high efficiency. The total active area of the photon detector is approximately 8 m/sup 2/.< >
