A '''klystron''' is a linear-beam [[vacuum tube]] which functions as an [[amplifier]], for fairly high frequency [[electro-magnetic]] radiation, such as [[microwave]]s. As an amplifier, it can be configured as a fairly powerful [[oscillator]], useable as a [[transmitter]].

In early [[radar]] work, it was replaced in that role by the [[cavity magnetron]], but klystrons were much used in [[receiver]]s, in their amplifier guise. Magnetrons are no longer favoured in that role, as their output frequency is too variable; improved klystrons have taken back over.

The klystron was invented in 1937 by [[Russell and Sigurd Varian]] (the former the idea man of the pair; the latter the fabricator). They later set up [[Varian Associates]] to produce klystrons, now seen as one of the founding events of [[Silicon Valley]].
