Abstract
LHCb, one of the four main experiments at CERN, is designed to study rare decays of charm and beauty hadrons to find evidence of New Physics. Charged hadron identification in LHCb is achieved by the Ring Imaging Cherenkov (RICH) detector, read out by Hybrid Photon Detectors (HPDs). The experiment will undergo an upgrade in 2019, after which it will be possible to reach luminosities up to 2 · 1033 cm−2 s−1 and a data readout frequency of 40 MHz. As a consequence, the electronics of almost all the sub-detectors will be modified or replaced accordingly to the new required performances. The RICH HPDs will be replaced with Multi-anode Photomultiplier Tubes (MaPMTs) and will be read out using an 8-channels ASIC, the CLARO. MaPMTs and electronics will be arranged in basic units, the first prototypes of which have been tested in charged particle beams at CERN. The geometry of RICH 1 will be changed to operate at higher luminosities. An overview of the LHCb RICH upgrade is presented
