摘要

本文介绍了一种利用欺骗局域表面等离子体（SLSPs）结构作为栅格的热离子栅格控制射频电子枪的创新设计。SLSP的强共振和高尺寸压缩能力使电子枪能够实现更小的电流、更紧凑的尺寸和最小的调制功率要求。该炮发射预调制脉冲电子束（EBs），重复频率为40GHz，峰值电流为18ma。仿真实验证明了该枪能够利用该预调制波束检测波束相互作用（BWI）过程中电子的相对相位。这种新颖的射频电子枪设计为未来检测行波管元件开辟了新的途径。

Design of an RF Electron Gun Featuring a Spoof Localized Surface Plasmon Grid

This article introduces an innovative design for a thermionic grid-controlled RF electron gun that utilizes a spoof localized surface plasmons (SLSPs) structure as the grid. The strong resonance and high size compression capabilities of SLSP enable the electron gun to achieve reduced current, compact dimensions, and minimal modulation power requirements. The gun emits pre-modulated pulse electron beams (EBs) with a 40GHz repetition rate and an 18 mA peak current. Simulation experiments demonstrate the gun’s capability to detect the relative phase of electrons in the beam-wave interaction (BWI) process using this pre-modulated beam. This novel RF electron gun design opens new avenues for future detection of TWT components.
