Klystron - Sperry Gyroscope Company |

Did you know that Sperry was assigned a trademark on the term "klystron?"The klystron vacuum tube type was actually invented in 1937 by American electrical engineers Russell and Sigurd Varian (I'm old enough to have had Varian Associates catalogs). According to this full-page advertisement in a 1944 issue of Radio News magazine, not only did Sperry develop the klystron vacuum tube, but they also coined a term to describe any study or application of it: "klystronics." Here is a very interesting excerpt from the Wikipedia page, "The work of physicist W.W. Hansen was instrumental in the development of the klystron and was cited by the Varian brothers in their 1939 paper. His resonator analysis, which dealt with the problem of accelerating electrons toward a target, could be used just as well to decelerate electrons (i.e., transfer their kinetic energy to RF energy in a resonator). During the second World War, Hansen lectured at the MIT Radiation labs two days a week, commuting to Boston from Sperry Gyroscope Company on Long Island. His resonator was called a "rhumbatron" by the Varian brothers. Hansen died of beryllium disease in 1949 as a result of exposure to beryllium oxide (BeO)." Klystron - Sperry Gyroscope Company
A pencil of energy beamed like light If you'll imagine an invisible search-light beam, you'll have a good picture of how Klystron-generated radio waves can be directed into a narrow "pencil" of energy. This direction is accomplished by suitable reflectors. The beam of ultra-high-frequency waves travels in a straight line, and it can pierce fog, smoke, and clouds which would stop a light beam. Sperry-developed Klystron tubes are used in many equipments now serving our Armed Forces. Later, Klystronics will open the door to the development of many ingenious peacetime devices. Klystrons are now being produced in quantities, and certain types are available. The name "KLYSTRON" is a registered trade-mark of the Sperry Gyroscope Company, Inc. Like many other Sperry devices, Klystrons are also being made during the emergency by other companies. Sperry Gyroscope Company Great Neck, N.

About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
