Single Photoelectron Spectra Analysis for the Metal Dynode Photomultiplier

This note deals with a method of single photoelectron analysis for the compactmetal dynode photomultipliers. The spectra taken by Hamamatsu R5600 and R5900photomultipliers have been analysed by the presented method. The detailed analysis shows that the method appropriately describes the process of chargemultiplication in those photomultipliers and can be used for finding of theirbasic internal parameters.
