microwave tube การใช้

• Silver-plated iron was used in early microwave tubes.
• Microwave tube designers used to take numerous steps to reduce microphonism in klystrons.
• In 1959 Bob Coulson established Traveling-wave tube and Microwave tube sections and they were producing ceramic hydrogen thyratrons as well.
• The Varians moved to the east coast in 1940 to work for Sperry, where wartime development of the microwave tube continued.
• At that time, the seven-year-old transistor and the components and better microwave tubes for aerospace and defense.
• In 1953, Ash and his partner, Tex Thornton, bought Litton Industries, a small West Coast producer of microwave tubes.
• Also in the 1950s, Sturrock invented a number of implements, including a novel microwave tube later dubbed the " Free electron laser ."
• His graduate research dealt with noise in microwave tubes and electron-stream instabilities ( which later became the basis of the Vircator high power microwave oscillator .)
• The klystron, a microwave tube, was noticed in 1938 by Sperry Gyroscope, who gave the Varian brothers and Hansen a contract to do further work.
• It finds application in electroplated conductors entering glass envelopes of electronic parts such as vacuum tubes ( valves ), X-ray and microwave tubes and some lightbulbs.
• They are used e . g . in electron microscopes, microwave tubes, electron lithography, electron beam welding, X-Ray tubes, and free electron lasers.
• Devices and techniques in which hexaboride cathodes are used include electron microscopes, microwave tubes, electron lithography, electron beam welding, X-ray tubes, and free electron lasers.
• The development of centimeter radar during World War 2 and the first high power microwave tubes, the klystron ( 1938 ) and cavity magnetron ( 1940 ), resulted in the first widespread use of waveguide.
• In the 1950s Sturrock researched nuclear physics at the Atomic Energy Research Establishment; plasma physics at St . Johns'College, Cambridge; microwave tubes at Stanford University; accelerator physics at the European Organization for Nuclear Research ( CERN ).
• The 6AV6 anode-grid capacitance is 2 picofarads ( pF ), the 7768 has a value of 1.7 pF . The close electrode spacing used in microwave tubes " increases " capacitances, but this increase is offset by their overall reduced dimensions compared to lower-frequency tubes.
• On leave from the University, he acted as head of the Microwave Tube Research Section of the Hughes Aircraft Company ( 1951 52 ), engaged in research in quantum electronics at the Bell Laboratories, Inc ., Murray Hill, New Jersey ( 1963 64 ) and held Visiting Professorship at the University of California, Santa Cruz and Stanford University.
