      Pierce’s book Traveling-Wave Tubes was published in Kompfner received a doctorate in physics from Oxford in and joined Pierce’s group at the Bell Laboratories the same year. Continuing work he had started in England, Kompfner developed a backward-wave oscillator and amplifier which could be tuned electronically. Pierce, "Traveling-Wave Tubes", New York: van Nostrand Co., ] He later recounted that "Rudy Kompfner invented the traveling-wave tube, but I discovered it." According to Kompfner's book, the statement "Rudi invented the traveling-wave tube, and John discovered it" was due to Dr. Eugene G. Fubini, quoted in "The New Yorker" "Profile" on.

    The invention of the free-electron laser has a fascinating history, dating mainly from the development of traveling wave vacuum tubes for high-power microwave generation in the early s. Klystrons, developed during World War II, were the first sources of coherent radiation from a free-electron beam. This book is concerned with the transmission of information by electrical means using semaphores, and reflected sunlight. The invention of the telegraph, a device for digital data transmission, preceded the invention of the telephone, an analog nonlinear amplifiers such as a File Size: KB.

Additional Physical Format: Online version: Kompfner, Rudolf. Invention of the traveling-wave tube. San Francisco, San Francisco Press [] (OCoLC) A traveling-wave tube (TWT, pronounced "twit") 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.

The TWT belongs to a category of "linear beam" tubes, such as the klystron, in which the radio wave is amplified by absorbing power from a beam of electrons as it. A traveling-wave tube (TWT) is an electronic device used to amplify radio frequency signals to high power, usually in an electronic assembly known as a traveling-wave tube amplifier (TWTA).

The bandwidth of a broadband TWT can be as high as three octaves, although tuned (narrowband) versions exist, and operating frequencies range from MHz to 50 GHz. According to Kompfner's book, the statement "Rudi invented the traveling-wave tube, and John discovered it" was due to Dr.

Eugene G. Fubini, quoted in The New Yorker "Profile" on Pierce, Septem Pierce is widely credited for saying "Nature abhors a vacuum tube", but Pierce attributed that quip to Myron : Stuart Ballantine Medal (), IEEE. Traveling-wave tube explained. A traveling-wave tube (TWT, pronounced "twit") 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.

The TWT belongs to a category of "linear beam" tubes, such as the klystron, in which the radio wave is amplified by absorbing power from. But the fruitful outcome was the invention of the traveling-wave tube, while trying to make a better klystrom amplifier for radar re- ceivers.

His fundamental idea the continuous interaction of an electron stream and an electromagnetic wave of the same velocity traveling along a helix was ingenious, and the realization worked.

Kompfner, and none as Rudolf. Rudi's success in a field that he himself chose is indubi- table; it is attested by numerous honors. In the Physical Society awarded him its Duddell Medal for his invention of the traveling-wave tube.

This led him to give a lecture and later to write a book on The Invention of the Traveling-Wave Size: 1MB. Millimeter-Wave Gyrotron Traveling-Wave Tube Amplifiers - Kindle edition by Du, Chao-Hai, Liu, Pu-Kun.

You can read his account of the invention in his book, The Invention of the Traveling-Wave Tube-that is, if you can find a copy.

A continuing theme of the book is that Rudi not only speculated; he built things, and he made measurements, looking for the expected and sometimes finding the unexpected. The team collected and read hundreds of papers on the history and evolution of the traveling-wave tube. First introduced in the s, a TWT is a relatively simple piece of equipment used for transmitting data across long distances, including the vast expanses of space.

These devices operate on different principles from low-frequency vacuum tubes, using the ballistic motion of electrons in a vacuum under the influence of controlling electric or magnetic fields, and include the magnetron (used in microwave ovens), klystron, traveling-wave tube (TWT), and gyrotron.

They are also used in microwave linear beam vacuum tubes such as klystrons, inductive output. Microwave Hall of Fame Part II. Go back to the first page of the Microwave Hall of Fame. In Kompfner invented the traveling wave tube, although his lab notebook shows he had the field lines sketched sketched incorrectly about the helix.

He moved to the United States after the war and worked at Bell Labs with John Pierce on other. A traveling wave tube (TWT) is an electronic device used to amplify high-power radio frequency signals.

The TWT was invented by Rudolf Kompfner in a British radar lab during World War II, and refined by Kompfner and John Pierce at Bell Labs. Both of them have written books on the device. According to Kompfner’s book, the statement "Rudi invented the traveling-wave tube, and John discovered it" was due to Dr.
