Description

Particle identification is the fundamental requirement of the LHCb experiment to fulfill its physics programme. Positive hadron identification is performed by two Ring Imaging CHerenkov (RICH) detectors. This system covers the full angular acceptance of the experiment and is equipped with three Cherenkov radiators to identify particles in the wide momentum range from 1 GeV/c up to 100 GeV/c. The Hybrid Photon Detectors (HPDs) located outside the detector acceptance provide the photon detection with 500,000 channels. Specific readout electronics have been developed to readout and processing data from the HPDs including data transmission and power distribution. A dedicated very high voltage control system has been implemented to operate and monitor the photon detectors. The operation and performance of the RICH system are ensured by the constant control and monitoring of low voltage and high voltage systems, of the gas quality and enviromental parameters, of the mirror alignment, and finally detector safety. The description of the LHCb RICH will be given. The experience to operate the detector at the Large Hadron Collider will be presented and discussed.
