摘要：
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(4)F(10) radiators and the second covers up to 100 GeV/c using CF(4). Cherenkov light will be detected using a novel type of position sensitive device: the pixel Hybrid Photon Detector (HPD). In the pixel HPD, photoelectrons are produced in a multialkali photocathode, accelerated and focused by an electrostatic field, and then detected by a pixelated silicon detector which is bump-bonded onto a 40 MHz read-out chip. This paper reports on the development of the LHCb RICH detectors and the performance of the HPDs.
