This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:Cathode ray tube diagram-en.svg|lang=en]] for the English
English: Diagram of JJ Thomson's experiment with cathode rays. Cathode rays (blue) emitted by the cathode on the left were defelcted by an electric field (yellow) in the center. Cathode rays (blue) emitted by the cathode on the left were defelcted by an electric field (yellow) in the center.
A diagram showing a Crookes tube connected to a high voltage supply. The Maltese cross has no external electrical connection. Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube.

A flying-spot scanner (FSS) uses a scanning source of a spot of light, such as a high-resolution, high-light-output, low-persistence cathode ray tube (CRT), to scan an image. Usually the image to be scanned is on photographic film , such as motion picture film , or a slide or photographic plate .
A teltron tube (named for Teltron Inc., which is now owned by 3B Scientific Ltd.) is a type of cathode-ray tube used to demonstrate the properties of electrons. There were several different types made by Teltron including a diode, a triode, a Maltese Cross tube, a simple deflection tube with a fluorescent screen, and one which could be used to ...
Schematic symbol used in circuit diagrams for a vacuum tube, showing control grid. The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode. The control grid usually consists of a cylindrical ...
