摘要
采用带状电子束是在毫米波和太赫兹波段产生大功率输出的一种重要方法,为了提高工作频率、提高输出功率、拓展工作频带,对带状电子束的形成、传输和收集以及新型慢波结构进行研究,是真空电子学的热点研究方向之一。本文概述了目前国内外带状电子束真空电子器件的研究动态和发展趋势,并提出了今后发展的若干建议。
It's an important way to provide high output power in millimeter-wave and THz wave band by using sheet electron beam.And it becomes one of the most active research directions to study the formation,transportation,and collection of the sheet electron beam and the novel slow wave structures,for increasing the operating frequency,improving the output power,and broadening the operating bandwidth.This article provides an overview of the research and development trends of the sheet electron beam vacuum devices at home and abroad,and puts forward several recommendations for future development.
