The LHCb RICH online monitor and data-quality

The LHCb experiment at the Large Hadron Collider has been optimised for high precision measurements of the charm and beauty quark sector. Efficient particle identification at high purities over a wide momentum range from around 1 to 100 GeV/c is vital to many LHCb analyses. Central to the LHCb particle identification strategy are two Ring Imaging CHerenkov (RICH) detectors. Rigorous monitoring of the RICH sub-detector is being developed to insure that high-quality data is recorded which meets the stringent demands from physics analyses.
