Studies of prepulses and late pulses in the 8 '' electron tubes series of photomultipliers

In this article we describe the main results of the study of prepulses and late pulses in the 8" Electron Tubes series of photomultipliers. Photomulti pliers with large hemispherical photocathodes are used widely in many large -scale underground and underwater experiments where precision timing plays a crucial role. The measurements carried out with the aim of demonstrating importance of PMT timing in the context of prepulses and late pulses. (C) 2 000 Elsevier Science B.V. All rights reserved.
