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 ...
Magnetron was made available for retrofitment to Briggs & Stratton engines made since 1963. Competitor Tecumseh had made a capacitor discharge ignition setup since 1968 for their cast iron engine models, expanding its availability and making it standard equipment on vertical shaft engines powering lawn mowers in late 1976, five years before the ...
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]
At war's end in 1945, the company had built about 80 percent of all magnetrons. Raytheon ranked 71st among U.S. corporations in the value of World War II military production contracts. [13] In 1945, Raytheon's Percy Spencer invented the microwave oven by discovering that the magnetron could rapidly heat food. In 1947, the company demonstrated ...
PFNs are used to produce uniform electrical pulses of short duration to power devices such as klystron or magnetron tube oscillators in radar sets, pulsed lasers, particle accelerators, flashtubes, and high-voltage utility test equipment.
Olivia Munn recently appeared on Monica Lewinsky’s “Reclaiming” podcast and revealed she once turned down an offer worth millions of dollars from a studio to sign an NDA after she endured a ...
