Novel cold cathode compact amplifier

Abstract

The invention relates to a novel cold cathode compact amplifier. The novel cold cathode compact amplifier includes a high frequency interaction system, an input structure, an output structure, a collector and a cold cathode electron gun, wherein the high frequency interaction system includes a housing and a cyclic slow wave structure; one end of the housing is in seal connection with the cold cathode electron gun, and the other end of the housing is in seal connection with the collector; the input structure is in seal connection with the housing in a manner of penetrating through the housing,and the input structure is arranged at one end, close to the cold cathode electron gun, on the housing; and the output structure is in seal connection with the housing in a manner of penetrating through the housing, and the output structure is arranged at one end, close to the collector, on the housing. The novel cold cathode compact amplifier utilizes the cold cathode electron gun as the electronsource, coordinates with the cyclic slow wave structure, and utilizes the high frequency field to perform density modulation on the electron beam, and then the modulated electron beam enters the highfrequency interaction system to interact with the high frequency electromagnetic field and realize energy exchange and amplification and output of signals, thus greatly reducing the cycle number of the cyclic structure, and reducing the volume of the electric vacuum amplification device and the device processing difficulty.
