Abstract	A code for simulation of photomultipier response was created and tested for a broad range of photomultiplier gain, A reasonably good agreement between the experimental R5900 spectra and simulated ones was achieved. It was shown that for correct explanation of the charge fluctuations in the observed R5900 single photoelectron spectra the dynode inhomogeneity was estimated and first dynode effect should be taken into account. The value of the inhomogeneity was estimated to be about 25%.
