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 frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...
A traveling-wave tube (TWT, pronounced "twit" [1]) or traveling-wave tube amplifier (TWTA, pronounced "tweeta") is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. [2] It was invented by Andrei Haeff around 1933 as a graduate student at Caltech, and its present form was ...
Sutton tube. The 5836, a typical reflex klystron used as a low-power microwave source. Note the terminal on the top of the tube, used to power the repeller. Sutton tube was the name given to the first reflex klystron, developed in 1940 by Robert W. Sutton of Signal School group at the Bristol University. The Sutton tube was developed as a local ...
Bay News 9. Bay News 9 (also officially known as Spectrum Bay News 9 as of September 24, 2017) is a cable news television network located in St. Petersburg, Florida. Owned by Charter Communications, it currently serves the Tampa Bay area including Hillsborough, Pinellas, Manatee, Polk, Pasco, Hernando, and Citrus counties.
An airport surveillance radar (ASR) is a radar system used at airports to detect and display the presence and position of aircraft in the terminal area, the airspace around airports. It is the main air traffic control system for the airspace around airports. At large airports it typically controls traffic within a radius of 60 miles (96 km) of ...
The main accelerator is buried 9 m (30 ft) below ground [15] and passes underneath Interstate Highway 280. The above-ground klystron gallery atop the beamline, was the longest building in the United States until the LIGO project's twin interferometers were completed in 1999. It is easily distinguishable from the air and is marked as a visual ...
A reflex klystron (1953) Russell and Sigurd founded Varian Associates in 1948, along with Hansen and Ginzton. They initially created the company to commercialize the klystron [2] and develop other technologies, such as small linear accelerators to generate photons for external-beam radiation therapy. They also were interested in nuclear ...
The reflex klystron is a klystron utilizing only a single apertured cavity resonator through which the beam of charged particles passes, first in one direction. A repeller electrode is provided to repel (or redirect) the beam after passage through the resonator back through the resonator in the other direction and in proper phase to reinforce ...
