what's a klystron tube?

Question

in simple words please, i tried some websites but they're not veery helpful cos they're a bit difficult to understand

Answer 1

klystron tube

A klystron is a specialized vacuum tube (evacuated electron tube) called a linear-beam tube. The pseudo-Greek word klystron comes from the stem form κλυσ- (klys) of a Greek verb referring to the action of waves breaking against a shore, and the end of the word electron.

The Varian brothers (Russel and Sigurd) of Stanford University are generally considered to be the inventors of the klystron. Their prototype was completed in August 1937. Upon publication in 1939, news of the klystron immediately influenced the work of US and UK researchers working on radar equipment. (The Varians went on to found Varian Associates to commercialize the technology.)
Usage

Klystrons are used as an oscillator or amplifier at microwave and radio frequencies to produce both low power reference signals for superheterodyne radar receivers and to produce high-power carrier waves for communications and the driving force for linear accelerators. It has the advantage (over the magnetron) of coherently amplifying a reference signal and so its output may be precisely controlled in amplitude, frequency and phase. Many klystrons have a waveguide for coupling microwave energy into and out of the device, although it is also quite common for lower power and lower frequency klystrons to use coaxial couplings instead. In some cases a coupling probe is used to couple the microwave energy from a klystron into a separate external waveguide.

Answer 2

It's an amplifier that is like a vacuum tube (what was used before transistors)
Very high power 100s or 1000s of watts of power. Some Klystron tubes are used for powering telecommunication sites in the 80s.

Answer 3

See http://www2.slac.stanford.edu/vvc/accelerators/klystron.html for a simpler illustration. The organ pipe is a good comparison. The klystron uses rigid metal chambers to enhance resonance and to withstand high power levels. A child on a swing can gain a lot of energy by adding just a little energy with each push. A resonant circuit, or an electromagnetic wave propagating in a klystron, works by continually transforming energy between electric and magnetic fields and back. At the resonant frequency, this happens with minimal loss. Less of the energy you add is wasted, and more is used to strengthen the electromagnetic waves.

Answer 4

A klystron is a specialized vacuum tube (evacuated electron tube) called a linear-beam tube.

It refers to the action of waves breaking against a shore.

Klystrons are used as an oscillator or amplifier at microwave and radio frequencies to produce both low power reference signals for superheterodyne radar receivers and to produce high-power carrier waves for communications and the driving force for linear accelerators. It coherently amplifies a reference signal and so its output may be precisely controlled in amplitude, frequency and phase.
