Kompfner first experimented with traveling-wave tubes that had the electron beam running outside the helix, as Haeff had done a decade earlier, the so-called deflection type of traveling-wave tube.

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.

traveling-wave tube[′travəliŋ ¦wāv ‚tüb] (electronics) An electron tube in which a stream of electrons interacts continuously or repeatedly with a guided electromagnetic wave moving substantially in synchronism with it, in such a way that there is a net transfer of energy from the stream to the wave; the tube is used as an amplifier or.

Helix Studies As mentioned in the last Progress Report, a large-scale model of the helix used in the traveling-wave tube was constructed. The phase velocities. Traveling-wave tube containing an electron gun, slowing down the system, consisting of a chain of linked cavities, input and output waveguide transitions with sealing dielectric plate, the focusing system in the form of electrical or permanent magnets and a collector, wherein the input and output waveguide transitions connected quarter wave.

The digit and digit formats both work. Traveling wave tubes (TWTs) New for December This page was split from our microwave tube page and we added some content and photos thanks to Terry Cisco. The TWT was invented by Rudolf Kompfner in in England, for this reason he appears in our Microwave Hall of Fame.
One of the main tasks on research traveling-wave tube (TWT) operating regimes is the simulation of the parametric code describing operation of TWT in a linear regime and a self-excitation. In this paper TWT operating in a linear regime with inhomogeneity of slow wave structure of device along interaction region is studied.
Travelling wave tube is a cylindrical structure which contains an electron gun from a cathode tube. It has anode plates, helix and a collector. RF input is sent to one end of the helix and the output is drawn from the other end of the helix.
An electron gun focusses an electron beam with the velocity of light. A magnetic field guides the beam. In a gyrotron traveling-wave tube amplifier (gyro-TWT) circuit, one of the cyclotron harmonic couples with an eigen wave mode. Such a beam-wave coupling forms a.
Other articles where Traveling-wave tube is discussed: electron tube: Traveling-wave tubes: These are generally used to amplify microwave signals over broad bandwidths. The main elements of a traveling-wave tube (TWT) are (1) an electron gun, (2) a focusing structure that keeps the electrons in a linear path, (3) an RF circuit that causes RF.
characteristics of the tube. In this report, only the helix type of traveling-wave tube will be considered. It consists of a cylindrical helical coil which, in the absence of an electron beam, is capable of supporting a wave along the axis of the helix with a phase velocity substan-tially less than the light velocity.
Abstract. Mathematical expressions showing that the optimum way of suppressing the self-excitation of a backward-wave traveling-wave tube is to decrease the diameter and pitch of the slow-wave structure toward the energy output are : A. Danilov, E. Il’ina, V. Kudryashov, I.
Polyakov. In a traveling-wave tube the kinetic energy of electrons is transferred to the power of an electromagnetic wave (RF-signal). Or phrased in other words. The electrons are decelerated and the electromagnetic field gets stronger. How does its work?.
We outline the main principles of the wave theory of interaction between an electron beam and waves in a slow-wave structure near the edge of the transmission band. Formulation of the basic equations and the boundary conditions is considered taking consistently into account that the interaction parameter is small.
A comparison of the results with a discrete Cited by: FIELD: electricity. SUBSTANCE: travelling wave tube (TWT) of ultrahigh-frequency range of wave lengths comprises an electron gun, a moderating system of "opposite pins" type, comprising connected cells, dielectric sealing partitions that separate the moderating system from microwave tracks, a focusing system in the form of a chain of permanent magnets and a collector.
In Nov. when there was a consensus to change title from traveling wave tube amplifier to traveling wave tube, Engineer Bob did that, but then also, without any prior suggestion or comment, took out the TWTA bits and made a new article that has remained unreferenced and nearly orphan.
I propose we merge it back in as a section or two. The traveling-wave tube was to be the focus of my activities, and of those of many others, until I abandoned work on vacuum tubes. Traveling-Wave Tubes Work on traveling-wave tubes occupied most of my time from until around a period of 13 years.
Practical travelling wave tube amplifiers (TWTAs) have applications in both receiver and transmitter systems, and come in all shapes and sizes, but they all consist of three basic parts-the tube, the tube mount (which includes the beam focussing magnets) and the power supply.Principles of Traveling Wave Tubes (Artech House Radar Library) [A.
