Meaning
A diode vacuum tube in which the flow of electrons from a central cathode to a cylindrical anode is controlled by crossed magnetic and electric fields; used mainly in microwave oscillators.
Classification
Nouns denoting man-made objects.
Examples
- The magnetron in the oven used microwave energy generated by its high-frequency output to heat the food.
- A team of engineers worked to optimize the efficiency of the magnetron's cathode for improved microwave production.
- In radar applications, magnetrons are often used to create the microwave pulses that bounce off targets.
- The powerful magnetron design created microwave radiation that could penetrate the walls for remote sensing.
- Due to limitations on production time, researchers scaled up their experiments with magnetrons for microwave production.
