Abstract:

Beam tests were performed in 1998 to investigate the performance of a prototype of the downstream RICH of the LHCb using hybrid photo-diodes and multi anode PMTs. The angular resolutions obtained from these photodetectors under various experimental configurations are compared with the expectations from simulation. (C) 1999 Elsevier Science B.V.

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

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment 433:1 (1999) 159-163

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.
