Paper Abstract

This tube is aimed at shuttering speeds faster than 200 picoseconds, with required electrical gate pulse less than 80 volts. Similar tubes were described in a 1984 paper at this meeting. One new feature is the use of a microchannel plate (MCP) to provide high and adjustable signal gain. This tube, in comparison with proximity-focussed tubes, conserves resolution by using an electrostatic focus lens. Also new is the use of transfer photocathode technique to eliminate stray emission from the gate mesh. Measured performance: Gating speed, Gain, On-Off signal ratio will be presented. Tube construction and the transfer photocathode technique will be discussed. The noise which shows up in high-gain imaging systems will be discussed.
