Title:
MICROWAVE ELECTRON TUBE, GETTER, MICROWAVE AMPLIFICATION DEVICE AND POWER SOURCE
Document Type and Number:
WIPO Patent Application WO/2018/151253
Kind Code:
A1
Abstract:
The objective of the invention is to provide a microwave tube, or the like, wherein gas adsorption action of a getter may be satisfactorily performed independently from a microwave amplification operation. In order to solve this problem, this microwave electron tube comprises: a helix wherein a microwave may progress oriented from an input section to an output section within a helical tube; an electron gun emitting an electron flow oriented toward the helix; a focusing device causing the electron flow to traverse the vicinity of the helix in the direction of a collector; the collector absorbing the electron flow; and a getter having a heater insulated from the cathode provided in the electron gun.
