Description
The use of SiPMs has been very early associated to readout ASICs as they were used in often large numbers to cover a reasonable area. OMEGA laboratory started in the early days to design readout ASICs for calorimetry in high enery physics, with chips as SPIROC or EASIROC/CITIROC. The performance and compactness provided by these ASICs helped to make the SiPM arrays easy to use. The excellent timing properties of SiPMs were quickly recognized and there again fast ASICs allowed to exploit this feature and were used in time of flight PET medical applications. More recently LHC upgrades at CERN make use of large quantites of SiPMs and need new ASICs to read them out at high rate.
The talk will start from the fundamental aspects of signal handling in SiPM to get the best charge and time measurements and show some examples and performance achieved with various chips developed by OMEGA and WEEROC.
