The LHCb RICH detectors use 484 Hybrid Photon Detectors (HPDs), each with an encapsulated 1024 pixel sensor, to detect the Cherenkov light. Three production modules of HPD arrays (one tenth of the total modules), have been tested using Cherenkov radiators in a charged particle beam. Each module cont
The LHCb Ring Imaging Cherenkov (RICH) counters use the pixel Hybrid Photon Detector (HPD) as a photo-sensitive device. Photo-electrons are produced in a semi-transparent multi-alkali photo-cathode (S20) and are accelerated by a voltage of 20 kV onto a pixelated silicon anode. The anode is bump-bond
The LHCb experiment at the CERN Large Hadron Collider employs two Ring Imaging Cherenkov (RICH) detectors for particle identification. The first covers the charged particle momentum range 1-60 GeV/c using aerogel and C 4F10 radiators and the second covers up to 100 GeV/c using CF4. Cherenkov light w
