Abstract
A klystron comprises an electron gun which emits electron beams, a cavity resonator which imparts velocity modulation to the electron beams, a cavity resonator which converts the power of the electron beams into microwave power, a drift tube interconnecting the cavity resonators, and a vacuum gate valve provided on the drift tube.
Claims1
A klystron comprising:
- an electron gun which emits electron beams;
- a collector for collecting the electron beams emitted by the electron gun;
- a plurality of cavity resonators including at least first and second cavity resonators arranged between the electron gun and the collector;
- said first cavity resonator being operable to establish a resonant condition to cause velocity modulation of the electron beams traveling from said electron gun and said second cavity resonator being operable to convert the beam power of the modulated electron beams into microwave power;
- a drift tube interconnecting said first and second cavity resonators and establishing a flow path for said electron beams between said first and second cavity resonators;
- and a vacuum gate valve positioned in the drift tube between said first and second cavity resonators to control the establishment of a vacuum condition in the portion of said drift tube between said gate valve and said electron gun and in said first cavity resonator and said electron gun.
