Abstract
It is considered model of a realistic photomultiplier (PM), allowing get by the producing function method in enough general event a new analytical expression for its response in broad range of
the light intensity. Seven free parameters of the model have a clear physical interpretation. Under stable equipment working and big statistics aproximating the PM response functions, got from
model by expressions, has much get good convergence that enables to receive the single electron parameters, gain, the average number of photoelectrons, noise with good accuracy. The
results are used in the study of longterm stability of the scintillation muon counters for the CDF II detector (Fermilab).
KEY WORDS: photomultiplier, Poisson distribution, Gauss distribution, background charge distribution, producing function, indicative function, average number photoelectrons, gain factor of
the photomultiplier.
