Latest beam test results from RICH prototypes using hybrid photo detectors and multi anode PMTs

Abstract:
Beam tests were performed to investigate the performance of a prototype of the downstream ring imaging counter (RICH) of the LHCb using hybrid photodiodes and multi-anode photomultipliers. The Cerenkov angle resolution obtained for the three types of photodetectors tested agreed well with the expectations from simulations. Using 61-pixel hybrid photodiodes, a single photon resolution of 0.35 mrad was attained and the particle identification capability was demonstrated.
