Abstract :
Construction of the Cherenkov detectors using the silica aerogel SP-30 (Matsushita) and fast photomultipliers is described. Application of these detectors for the luminosity measurement in the ZEUS experiment at HERA is then presented. The HERA luminosity is measured using high rate, high-energy bremsstrahlung photons, and the Cherenkov detectors are designed for achieving the required resolution of the photon energy measurement.
