Example sentencesExamples
- You remember there had been developed in my laboratory by Randall and Boot, a cavity magnetron which made microwave radar possible and I went to America in connection with the early days of this.
- Randall had set up the unit on the basis of his wartime reputation, having developed (with Henry Boot) the cavity magnetron, the heart of airborne radar and a crucial element in the Allies' narrow victory in the battle of the Atlantic.
- Should absorption not take place - if, for example, the oven is activated when empty, some energy will re-enter the waveguide and cause over-heating of the magnetron.
- In 1940, aided by John Randall and Henry Boot from Birmingham University, Watson-Watt invented the cavity magnetron.
- Today, magnetrons are used as the source of heat in microwave ovens.

Origin

1920s: from magnetic + -tron from electron.
