The cavity magnetron is a power RF oscillator device in which electrons are induced to move in a circular path through a tuned cavity, inducing a high-power RF field, and it lies at the heart of a ...

[Curious Droid] is back with a history lesson on one of the most important inventions of the 20th century: The cavity magnetron. Forged in the fighting of World War II, the cavity magnetron was the… ...

How a Raytheon Scientist Accidentally Invented the Microwave Oven The microwave has a messy origin story. That’s how innovation works sometimes.

Coupled with novel SRF cavity materials and off-the-shelf cooling equipment, magnetrons also could help open the door to larger industrial and commercial markets.

Magnetron powered EM-drive construction expected to take two months Paul March indicates that Eagleworks NASA has started the build of their 1.2kW magnetron powered EM-Drive prototype in a ...

Over all those many decades, though, the heart of the microwave oven has stayed the same. It is the cavity magnetron, developed during WWII for radar. It is big, heavy, and inefficient.

Original cavity magnetron as used to develop radar. Mrjohncummings, CC BY-SA At the heart of radar technology is the “ magnetron,” the device that produces the radio waves.

The cavity magnetron's invention changed the world." Because Britain had no money to develop the magnetron on a massive scale, Churchill had agreed that Sir Henry Tizard should offer the magnetron to ...
