Abstract
The front-end (Level-0) electronics interface module for the LHCb Ring Imaging Čherenkov (RICH) detectors is described. This module integrates the novel hybrid photon detectors (HPDs), which instrument the RICH detectors, to the LHCb trigger, data acquisition (DAQ) and control systems. The system operates at 40MHz with a first-level trigger rate of 1MHz. The module design is presented and results are given for both laboratory and beam tests.
