Abstract
A prototype of the LHCb ring imaging Cherenkov detector has been constructed. The prototype module contained a pre-production pixel hybrid photon detector, mounted on the final photon detector mechanics. The photon detector was read out at the full LHC speed of 40 MHz using the full prototype on-detector RICH electronics readout chain. The readout uses radiation-tolerant FPGA technology, 1.6 GHz optical links and 40 MHz trigger-timing and control (TTC). The photon detector was mounted in a gas vessel and Cherenkov rings have been observed from an N/sub 2/ radiator using electron and pion beams.
Highlights
T HE LHCb experiment [1] will make high precision studies of CP violation and other rare phenomena in B meson decays
The photon detector solution adopted for the LHCb Ring Imaging CHerenkov (RICH) detectors, is the novel Pixel Hybrid Photon Detector (HPD) which has been developed in close collaboration with industry
Using 10GeV/c electron and pion beams from the CERN-PS T9 facility, the photon detector performance has been observed to be similar to that seen in the laboratory
Summary
T HE LHCb experiment [1] will make high precision studies of CP violation and other rare phenomena in B meson decays. In order to provide this capability, two Ring Imaging CHerenkov (RICH) detectors will be employed [2]. Photon detector prototypes that satisfy these constraints have been developed and subjected to extensive laboratory and beam tests. A prototype RICH detector, employing pre-production photon detectors with their associated mechanics, cooling and insulation, together with the prototype on-detector readout electronics, has been constructed to test these integration issues. This paper reports the first of two phases of test beam operation of this prototype. The photon detectors and the prototype RICH detector are described together with solutions to some of the integration issues. The results from the first phase of test beam operation are presented and the programme for the second phase is described
