I've been having some trouble modeling shot noise for a photomultiplier tube on Mathematica - I know that I have to use a random number generator and the Poisson distribution to do it, but I'm having trouble synthesizing everything. (There are many things I'm going to leave just as parameters, such as the average photon incidence rate, the quantum efficiency of the PMT's photocathode, the number of dynodes in the PMT.) I'm trying to basically model the voltage sequence that is outputted from the PMT. This article says that I should superimpose all the inflowing shots (along with an exponential decay of the shot). Would really appreciate some direction on putting it together in Mathematica. Thanks!
