two-cavity klystron Two-cavity klystron.

A klystron is an electron tube used to generate or amplify microwaves by controlling the speed of electrons. In a two-cavity klystron, electrons are accelerated and pass through a gap in a resonator. A radio-frequency field in this gap causes the electrons to bunch together. As these bunched electrons pass through a second resonator's gap, they induce a strong signal. Klystrons are utilized in ultrahigh-frequency (UHF) television transmission and microwave radar systems, capable of producing oscillations up to 400 gigahertz.123
