Optical systems for Ring Imaging Cherenkov (RICH) detectors have historically taken a variety of designs. Nowadays, technological developments allow more flexibility in the design and construction than was possible in the past, such as lightweight secondary mirrors that can be placed in the acceptance of an experiment, widespread use...

The housing of the photo-detectors for future Ring Imaging Cherenkov detectors is a complex task, regardless of the sensor choice, due to the many requirements. The sensor housing for LHCb Upgrade II will be an evolution of the one developed for Upgrade I where a totally modular solution, based on fully autonomous functional units called...

The limitations in performance of the present RICH system in the LHCb experiment are given by the natural chromatic dispersion of the gaseous Cherenkov radiator, the aberrations of the optical system and the pixel size of the photon detectors. Moreover, the overall PID performance can be affected by high detector occupancy as the pattern...
