Nonlinearity and Saturation
Talk
SiPM is an inherently nonlinear detector. Nonlinearity and saturation effects are originated from excess random losses of photon detection events due to a limited number of SiPM cells and non-instant recovery of the cells. From a statistical point of view, SiPM nonlinearity and saturation could be completely characterized by a probability distribution of a SiPM response in a required range of...

Nonlinearity and Saturation
Talk
Silicon Photomultiplier (SiPM) is often considered at the basic level as an array of Geiger mode APD cells which are connected in parallel, operate independently, and produce a sum of binary signals equal to number of fired cells. However, many specific effects make SiPM much more complicated device than just a collection of independent GM APDs.
Namely, during Geiger discharge and recovery of...

Nonlinearity and Saturation
Talk
We present a new method, Double Light Superposition (DLS) to characterize the dynamic range (DR) of silicon photomultipliers (SiPMs). This self-calibrated technique does not need the calibration procedures for the intensity of the light source from single photon to the level of SiPM saturation, makes the measurement easy and robust, thus can be a candidate of standard for DR measurement of...

Nonlinearity and Saturation
Talk
We present the experimental method and a corresponding setup to measure the response of SiPM as a function of incoming light intensity. In particular, the saturation behavior is investigated. The method introduces a calibrated quantity to measure the incoming number of photons independently of the photon detection efficiency and the optical crosstalk of the SiPM. In this way, different sensors...
