The cavity magnetron is a high-power vacuum tube used in early radar systems and subsequently in microwave ovens and in linear particle accelerators. A cavity magnetron generates microwaves using the interaction of a stream of electrons with a magnetic field , while moving past a series of cavity resonators , which are small, open cavities in a ...
Original cavity magnetron, 1940. This was developed by John Randall (1905-1984) and Harry Boot (1917-1983) at Birmingham University. Radars that could produce clear images of distant objects played a decisive role in World War II, by bouncing powerful, ultra-short radio waves off their targets.
The cavity magnetron was a crucial component in the development of short wavelength radar during World War II. [8] In 1937–1940, a multi-cavity magnetron was built by British physicist Sir John Turton Randall, FRSE and coworkers, for the British and American military radar installations in World War II. [ 9 ]
When a resonant cavity is perturbed, e.g. by introducing a foreign object with distinct material properties into the cavity or when the shape of the cavity is changed slightly, electromagnetic fields inside the cavity change accordingly. This means that all the resonant modes (i.e. the quasinormal mode) of the unperturbed cavity slightly change ...

As the "cavity magnetron" is what is most commonly thought of when "magentron" is mentioned, I think that it stands best as it is. Leonard G. 02:47, 10 Mar 2005 (UTC) Mention could be made of the Japanese invention of the cavity magnetron see "The main reason the Japanese effort remained unknown was because it lagged so far behind Allied and ...
The cavity magnetron is a vacuum tube with a filament in the center of an evacuated, lobed, circular cavity resonator. A perpendicular magnetic field is imposed by a ...
Cavity is an American sludge metal band from Miami, Florida. [1] They first formed in 1992, releasing a multitude of albums and singles before breaking up in 2003. [ 2 ] Steve Brooks and Juan Montoya would go on to play in Torche and Floor .
