Development of an integrated housing for Silicon Photomultipliers for future Ring Imaging Cherenkov photo-detectors

Description

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 Elementary Cells has been adopted. The main challenge of the new Elementary Cell will be to include active cooling. With SiPM, cooling well below zero degrees centigrade is required. Two different cooling strategies are considered and the status of the design for the Upgrade II Elementary Cell is presented.
