A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range.

2019年12月26日 · A Klystron (also known as a Klystron Tube or Klystron Amplifier) is a vacuum tube that is used to oscillate and amplify microwave frequency signals. It was invented by American electrical engineers Russell and Sigurd Varian.

Klystron, thermionic electron tube that generates or amplifies microwaves by controlling the speed of a stream of electrons. The electrons are originally accelerated to high velocity by a potential of several hundred volts and enter a narrow gap that forms part of a cavity resonator system (see

What is a klystron? Klystrons are high power microwave vacuum tubes. They are velocity-modulated tubes that are used in radars as amplifiers or oscillators. A klystron uses the kinetic energy of an electron beam for the amplification of a high-frequency signal.

This year marks the 60th anniversary of the birth of the klystron at Stanford University. The tube was the first practical source of microwaves and its invention initiated a search for increasingly more powerful sources, which continues to this day. This paper reviews the scientific uses of the klystron and outlines its operating principles.

The Klystron is a vacuum tube used to amplify small signals up to a high power levels applicable in radar, deep-space satellite communications and coherent RF power sources in applications like linear particle accelerators. Klystrons generally operate in the microwave radio frequency bands, but some applications have used Klystrons as low in ...

2025年1月17日 · A Reflex Klystron is a type of vacuum tube used to generate and amplify microwave signals. It operates on the principle of velocity modulation of an electron beam.

2019年10月3日 · Klystrons are linear-beam vacuum tubes used to amplify radio frequencies. The devices are effective over a broad range of frequencies ranging from hundreds of MHz (i.e., UHF) to hundreds of GHz (i.e., W-band microwaves and above). Klystrons operate at narrow bandwidths, typically between 1% and 10%, with high gain (e.g., 60 dB or more is possible).

Definition: Klystrons are a special type of vacuum tubes that find applications as amplifiers and oscillators at microwave frequencies. Its principle of operation is velocity modulation. Thus the device used for amplifying microwave signals is known as Two-cavity Klystron.

2023年10月26日 · Klystrons are specialized vacuum tubes that generate and amplify high-frequency electromagnetic waves, specifically in the microwave range. They play a critical role in various applications such as radar systems, satellite communication, medical accelerators, and particle accelerators for scientific research.
