ABSTRACT Collectors are an indispensable part of any vacuum microwave devices where the electron beam – so-called spent electron beam emerged from interaction structure – is collected. Although the first publication on depressed collectors dates back to 1940s, several evolving researches are still being carried out on collectors till date. The incessant publications from researchers all over the globe reveal the fact that this field has much more potential and vigor to be explored. The outcome of such intensive and diversified research has been in achieving several novel design variants in the geometry, different computer-aided modeling and design optimization techniques, innovative methods to counter/suppress secondary electrons. This comprehensive review has been intended to cover all the major research findings consolidating them at one place so that it could be beneficial to any new reader in this field, thereby further research progress may be accelerated.

慢波器件受压集热器综合评述

摘要 收集器是任何真空微波设备不可或缺的一部分，其中电子束——所谓的从相互作用结构中出现的废电子束——被收集起来。尽管关于沮丧的收藏家的第一本出版物可以追溯到 1940 年代，但迄今为止仍在对收藏家进行一些不断发展的研究。全球研究人员不断发表的论文表明，该领域有更多的潜力和活力有待探索。这种密集和多样化研究的成果是在几何形状、不同的计算机辅助建模和设计优化技术、对抗/抑制二次电子的创新方法中实现了几种新颖的设计变体。
