Comparison of Methods to analyze Crosstalk of Silicon Photomultipliers — •Lukas Maderer, Patrick Hufschmidt, Judith Schneider, Michael Wagenpfeil, Tobias Ziegler, and Thilo Michel — ECAP Uni Erlangen

Silicon Photomultipliers are devices for detection of low light intensities. An important parameter when characterizing these devices is the probability for correlated avalanches. Especially Crosstalk can be a problem for single photon measurements. Since there are multiple methods of analyzing Crosstalk present in literature leading to different results, we compare several of them based on the same data. One method measures the probability that a Crosstalk occurs, while the other one focuses on the mean number of Crosstalk events per initial avalanche. The first method yields to a linear dependency on the overvoltage, the second one to a quadratic dependency.
