Abstract
A solid-state photomultiplier is provided for use in imaging detectors. The solid-state photomultiplier includes a plurality of microcells configured to detect impinging photons. Each of the plurality of microcells further includes a photodiode coupled to a common electrode through a quenching resistor and configured to convert the impinging photons into electrical signals, and an impedance device coupled in parallel with the quenching resistor so as to reduce overall quenching impedance at high frequency. Further, techniques are provided for implementing low impedance device with controllable value to the SSPM for optimized timing resolution.
