Query: Beam test results for the upgraded LHCb RICH optoelectronic readout
  system   Starting from 2018, the LHCb detector will be upgraded to operate at higher
luminosity and extend its potential for new discoveries. The Ring Imaging
Cherenkov (RICH) detectors are one of the key components for particle
identification of the LHCb detector and the upgraded specifications will
require a redesign of the optoelectronic readout chain. In the present work, we
describe the experimental setup and the results of the tests carried out with a
particle beam to assess and validate the performance of the optoelectronic
readout system.
