While we now think of a magnetron as a microwave oven component, they are important in many microwave devices including radar. They are interesting because all they can do is oscillate.

Forged in the fighting of World War II, the cavity magnetron was the heart of radar signals used to identify attacking German forces. The magnetron itself was truly an international effort ...

The film discusses the function and operation of microwave oscillators in radar systems, focusing on the importance of oscillators like the magnetron and reflex velocity modulated tubes.

Without the cavity magnetron it is more than doubtful whether micro-wave radar could have become the decisive weapon it turned out to be. In this sense, therefore, the volume under review is ...

Invented during the height of the Battle of the Atlantic, the cavity magnetron resembles the vacuum ... than the radio waves previously used for radar defences. The post-war period saw a ...

Developed during World War II in the highest secrecy by the British, then brought to the U.S. to be optimized and made manufacturable in volume, this 500-MHz magnetron was key to early radar units.
