The LHCb Ring-Imaging Cherenkov (RICH) system is essential for Particle Identification (PID) of charged hadrons in the momentum range 2–100 GeV/c: it consists of an upstream detector (RICH 1), located close to the interaction point, and a downstream detector (RICH 2), placed after the tracking system. The LHCb experiment has been upgraded to deal with a five-fold increase in instantaneous luminosity, up to $2 \times 10^{33}\; cm^{-2}\; s^{-1}$, and to read out data at a rate of 40 MHz during RUN3. Both RICH detectors have been upgraded to maintain and excellent PID with a redesigned opto-electronic chain and new photon detectors. In addition, RICH 1 has a modified layout with new mechanics and spherical mirrors to reduce the maximum occupancy. The RICH system has taken part in all stable beams collisions throughout 2022. The RICH detectors are currently fully functional, time aligned, and integrated into the run control with all the other LHCb sub-detectors. The first data taken in the nominal RUN3 conditions seem promising and preliminary studies show an improved or equal PID performance compared to the one achieved in RUN2. An overview of the LHCb RICH system commissioning campaign is given, following all the steps from the first quality assurance measurements up to the current status of the detectors in the LHCb cavern
The LHCb experiment is preparing for an upgrade during the second LHC long shutdown in 2019-2020. In order to fully exploit the LHC flavour physics potential with a five-fold increase in the instantaneous luminosity, a trigger-less readout will be implemented. The RICH detectors will require new photon detectors and a brand new front-end electronics. The status of the integration of the RICH photon detector modules with the MiniDAQ, the prototype of the upgraded LHCb readout architecture, has been reported. The development of the prototype of the RICH Upgrade Experiment Control System, integrating the DCS and DAQ partitions in a single FSM, has been described. The status of the development of the RICH Upgrade Inventory, Bookkeeping and Connectivity database has been reported as well.
