Models of the signal response from SiPMs and PMTs — •Oleg Kalekin — Friedrich-Alexander-Universität Erlangen-Nürnberg, ECAP

New model of the single photoelectron charge distribution from PMTs is presented. This model features the asymmetrical shape of the distribution with a high tail towards small amplitudes in contrast to the simple Gaussian distribution frequently used. New model of the SiPM signal response with cross-talk is presented. Influence of the cross talk is modelled with a multinomial distribution. This model demonstrates good results when fitting the SiPM signal charge distribution.
