Abstract
The pixel Hybrid Photon Detector (HPD) has been developed to detect the light produced by the two Ring Imaging Cherenkov (RICH) detectors of the LHCb experiment. The device is a vacuum photon detector equipped with cross-focussing electron optics and a custom anode for photoelectron detection. The production of the 500 such devices that are required to cover the photon detection surface of the LHCb RICH detectors is ongoing. A pre-series of HPDs has been manufactured and their performance assessed in the laboratory. Successful operation has also been confirmed in a test beam. Accelerated ageing tests performed on one pre-series tube show no degradation of performance.
