  ABSTRACT: 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°<θ<35°). 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 ~170 nm to ~200 nm (7.3-6.2 eV) are detected with high efficiency. The total active area of the photon detector is ~8 m²

  ABSTRACT: The front-end readout electronics chain of the forward ring imaging Cherenkov (FRICH) detector used at the Delphi experiment of the Large Electron Positron (LEP) collider is presented. The system incorporates a wideband low-noise preamplifier, mounted in the proximity of the multiwire proportional chamber, an amplifying-discriminating-multiplexing FASTBUS unit for further signal amplification, discrimination, and channel reduction, and a LEP time digitizer FASTBUS unit for time digitization. The detector and its electronics are discussed, with particular emphasis on the novel characteristics and capabilities of the system

  ABSTRACT: The Forward Ring Imaging Cherenkov detector of the DELPHI experiment at LEP provides hadron identification at polar angles15° < θ < 35° and 145° < θ < 165°. Two radiator media, a layer of liquid C6F14 and a volume of gaseous C4F10, in combination provide coverage of momenta up to 40 GeV/c. A single array of photosensitive Time Projection Chambers registers the impact points of ultraviolet photons from both radiators. The design of the detector and of its readout system is described. First results obtained with a partly installed detector are reported.
