When installed, the tube projects through holes in the center of the cavity resonators, with the sides of the cavities making contact with the metal rings on the tube. A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio ...
The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. [ 1 ]
Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
Here the photos of an unbased Sutton tube used in the development of the external tuner and an Air Ministry 10E7501 complete with the tuner. The reflex klystron is a type of vacuum tube used to generate microwaves. It is a low-power device used primarily for two purposes: one is to provide a tuneable low-power frequency source for the local ...
The klystron, a microwave tube, [20] was noticed in 1938 by Sperry Gyroscope, who gave the Varian brothers and Hansen a contract to do further work. [17] The Varians did not know that the British were also working on early radar technology, which by then could detect submarines, but could not be made light enough to use in airplanes. [ 10 ]

Humanitarian officials and some US officials argue that the US is ceding influence to China in South and Central America because of Trump’s policies like the foreign aid freeze, which they say ...
Two microwave cavities (left) from 1955, each attached by waveguide to a reflex klystron (right) a vacuum tube used to generate microwaves. The cavities serve as resonators (tank circuits) to determine the frequency of the oscillators
