Abstract

The present and next generation of HEP experiments requires RICH detectors able to stand high beam intensities and trigger rates and to handle complex, crowded events: fast RICHes are needed. In the context of the future requirements of the enlarged luminosity of the COMPASS experiment, we are building a fast RICH detection system, with photon detection based on multianode photomultipliers and a system of lenses to collect the light from a much larger surface and to guide it to the PMT photocathode, preserving the position information. Albeit this approach is not new, we exploit a surface ratio of the order of 7, thus keeping the costs of the photon detection system reasonable, and we emphasize the fast response of the detectors and the associated electronics. We report about test beam results and laboratory studies of the multianode PMT performances.
