PV-400

The streak tube was specially produced for its streak mode applications in lidar-type systems of plasma diagnostics for thermonuclear units of takomak-type. In order to obtain an effective registration of input signals contained few quantums streak tube is provided by a wide-measure slit photocathode and an electron lens that squeezes an image of the signal at a blue/green phosphor screen applied on a fiber-optic disk. A pair of deflecting plates is made as two broadband communicational lines with coaxial connectors of 50Ohm wave resistance.
