The LHCb experiment at the CERN Large Hadron Collider (LHC) utilises two Ring Imaging CHerenkov (RICH) detectors for particle identification.To verify that the RICH assembly will perform as expected prior to installation, an array of 48 production Hybrid Photon Detectors (HPD) and their readout have been tested under realistic running conditions in a25ns-structured charged particle beam provided by the SPS facility at CERN. This system test is an important milestone in the overal lcommissioning of the LHCb detector and demonstrates that all aspects meet the stringent physics requirements of the LHCb experiment.

Abstract
The LHCb experiment at the CERN Large Hadron Collider (LHC) utilises two Ring Imaging CHerenkov (RICH) detectors for particle identification.To verify that the RICH assembly will perform as expected prior to installation, an array of 48 production Hybrid Photon Detectors (HPD) and their readout have been tested under realistic running conditions in a25ns-structured charged particle beam provided by the SPS facility at CERN. This system test is an important milestone in the overal lcommissioning of the LHCb detector and demonstrates that all aspects meet the stringent physics requirements of the LHCb experiment.
