Abstract
In a streak tube wherein a photocathode and an acceleration electrode are disposed in confronting relation to each other for accelerating a photoelectron beam emitted from the photocathode, at least one of the photocathode and the acceleration electrode is formed on a strip-like electrode. A pulse voltage is applied to the strip-like electrode, whereby a very intensive pulsed electric field is developed between the photocathode and the acceleration electrode with the application of a relatively low pulse voltage. Interactive regions of the photocathode and the acceleration electrode are closely position with high accuracy. The streak tube can thus generate a streaked image with a very high time resolution without an increase in the background emission on a phosphor screen.
