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 ...
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.
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 ...
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 ...
Nebraska has 93 counties.They are listed below by name, FIPS code and license plate prefix. Nebraska's postal abbreviation is NE and its FIPS state code is 31.. When many counties were formed, the bills establishing them did not state the honoree's full name; thus the namesakes of several counties, including Brown, Deuel, Dixon, and possibly Harlan, are known only by their surnames.
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 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] The primary commercial use of IOTs is in UHF television ...
A gyrotron is a class of high-power linear-beam vacuum tubes that generates millimeter-wave electromagnetic waves by the cyclotron resonance of electrons in a strong magnetic field. Output frequencies range from about 20 to 527 GHz, [1][2] covering wavelengths from microwave to the edge of the terahertz gap.
