Method for precise analysis of the metal package photomultiplier single photoelectron spectra

Abstract A sophisticated photomultiplier response function was suggested for single photoelectron analysis of the compact metal package photomultiplier spectra. The spectra taken by Hamamatsu R5600 photomultipliers have been analysed by the presented method. The detailed analysis shows that the method appropriately describes the process of charge multiplication in these photomultipliers and can be used to find their basic internal parameters.
