Cherenkov-light detectors for LHC-B: an application for Hybrid Photodetectors

The Ring Imaging CHerenkov detectors proposed for the CERN LHC-B experiment will need photon detectors with challenging specifications. Single photon sensitivity, millimetre precision and timing resolution adequate to resolve the LHC bunch-crossing period of 25 ns are required. The Hybrid Photodetector offers a promising solution.
