Description
Silicon Photomultipliers (SiPMs) have been able to replace Photomultiplier Tubes (PMTs) and Avalanche Photodiodes (APDs) in many applications as they have significant advantages in some key aspects, especially the very high quantum efficiency compared to the established PMTs and the much higher gain (and lower excess noise factor) compared to APDs. However, SiPMs application in large area and fast detectors is an open question as the detector capacitance severely degrades performances (lower signal to noise ratio, worse timing resolution, wider pulse shape and therefore higher pile-up). We will present several developments which try to overcome this limitation. Those include Application Specific Circuits (ASICs) and a proposal for new generation of hybrid photosensors.
