Time Resolution Performance Studies of Contemporary High Speed Photomultipliers

Abstract
The time resolution capabilities of prototype microchannel plate and static crossedfield photomultipliers have been investigated. Measurements were made of electron transit time, rise time, time response, single photoelectron time spread and multiphotoelectron time spread for LEP HR350 proximity focused high gain curved microchannel plate and VPM-154A/1.6L static crossed-field photomultipliers. The experimental data have been compared with results obtained with conventionally designed RCA 8850 and C31024 high speed photomultipliers. Descriptions are given of both the measuring techniques and the measuring systems.
