Webcontrol klystron efficiency and maximum power output. At low anode voltages bunching occurs at frequencies above the cutoff mode of the klystron bore tube and may allow the klystron to self oscillate at frequencies which will cause klystron failure. This requires that anode voltage not be applied below ≈200 kV. 2.2 Amplitude Modulator WebA klystron * is an electron tube in which the following processes may be distinguished: (A) Periodic variations of the longitudinal velocities of the electrons forming the beam in a …

How Reflex Klystron works - Electrical Engineering Stack Exchange
Webperformance of the tube more than any other part is the electron gun. The main part of the gun is the . cathode. that is made of porous tungsten impregnated with mix of barium … The reflex klystron (also known as a Sutton tube after one of its inventors, Robert Sutton) was a low power klystron tube with a single cavity, which functioned as an oscillator. It was used as a local oscillator in some radar receivers and a modulator in microwave transmitters in the 1950s and 1960s, but is now … See more A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, which is used as an amplifier for high radio frequencies, from UHF up … See more Klystrons amplify RF signals by converting the kinetic energy in a DC electron beam into radio frequency power. In a vacuum, a beam of electrons is … See more In all modern klystrons, the number of cavities exceeds two. Additional "buncher" cavities added between the first "buncher" and the "catcher" … See more Some klystrons have cavities that are tunable. By adjusting the frequency of individual cavities, the technician can change the operating frequency, gain, output power, or bandwidth of the amplifier. No two klystrons are exactly identical (even when … See more The klystron was the first significantly powerful source of radio waves in the microwave range; before its invention the only sources were the Barkhausen–Kurz tube See more The simplest klystron tube is the two-cavity klystron. In this tube there are two microwave cavity resonators, the "catcher" and the "buncher". When used as an amplifier, the weak microwave signal to be amplified is applied to the buncher cavity through a coaxial … See more The gyroklystron is a microwave amplifier with operation dependent on the cyclotron resonance condition. Similarly to the klystron, its … See more tecday lerbermatt
