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.
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.

The first commercially made electronic TV sets with cathode-ray tubes were manufactured by Telefunken in Germany in 1934. [32] [33] In 1947, the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to incorporate a cathode-ray tube screen, was created. [34]

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 ...
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 ...
