单词	klystron
释义	klystron An electron tube that generates or amplifies microwaves by velocity modulation . Several types are used; in the simple two-cavity klystron a beam of high-energy electrons from an electron gun is passed through a resonant cavity, where it interacts with high-frequency radio waves. This microwave energy modulates the velocities of the electrons in the beam, which then enters a drift space where the faster electrons overtake the slower ones to form bunches. The bunched beam now has an alternating component, which is transferred to an output cavity and thence to an output waveguide
