Abstract
The amplitude distribution of prepulses - those pulses preceding ion afterpulses in photomultipliers - depends upon the point of origin of the afterpulse. This fact provides a method of confirming the discovery that, in RCA types 8850 and 8852, afterpulses were formed throughout the photomultiplier. A simple theory of afterpulse formation in the region between the cathode and the first dynode is used to derive the prepulse height distribution.Keywords
