SIO Reference 59-11. This paper suggests a method for fitting the secondary emission characteristic of multiplier phototubes to a general equation for secondary emission from metalic surfaces. An analysis of this equation affords an explanation of the observed fact that multiplier phototube gain is proportional to the n-th power of the dynode supply voltage over a limited range.The technique followed was to develop an approximate form of the theoretical secondary emission characteristic, and then to correlate this analysis with an experimental determination of this characteristic for a specific 931-A multiplier phototube*/
