The LHCb RICH detectors: Operations and performance

The LHCb experiment has collected an unprecedented data sample to investigate beauty and charm hadrons decays. One of its key detector components is the RICH system providing excellent particle identification (PID) over a wide momentum range (2–100 GeV/c). Last year for the first time the RICH detec...

Sumario:The LHCb experiment has collected an unprecedented data sample to investigate beauty and charm hadrons decays. One of its key detector components is the RICH system providing excellent particle identification (PID) over a wide momentum range (2–100 GeV/c). Last year for the first time the RICH detectors have been operated in the automatic LHCb online alignment framework that, together with the well established calibration system, provided an excellent performance. The operations and performance of the RICH system during Run II are presented together with the activities performed during the winter shutdown to prepare for the last running period of the current RICH detectors before the LHCb upgrade.
