Title:
マイクロ波管及びその制御方法
Document Type and Number:
Japanese Patent JP7255920
Kind Code:
B2
Abstract:
There are provided a microwave tube that can contribute to keeping the high frequency output of the microwave tube constant for a long period of time without complex structure or adjustment and a method for controlling the same. The microwave tube comprises an electron gun that emits an electron beam; a magnetic circuit that focuses the electron beam emitted from the electron gun; a collector that captures the electron beam that has passed through the magnetic circuit; a high frequency circuit that is spirally arranged around the electron beam focused by the magnetic circuit and that transmits a high frequency; and a magnetic body part arranged around the electron gun so as to be movable in an emission direction of the electron beam, wherein a high frequency output from the high frequency circuit is controlled to be constant by moving the magnetic body part in an emission direction of the electron beam.
