论文摘要
我们介绍了THZ驱动的场发射电子枪的设计，制造和低功率测试。两个电池驻波枪设计为由110 GHz旋转式供电，并生产具有500 kW输入功率的360 keV电子。使用高精度钻石旋转的曼德斯和铜电饰制造了几种枪支结构。现场发射源是铜尖端，半径为50 $ $ m的半径插入了第一个单元格。使用方位角压缩对空腔共振的频率进行机械调节。这项工作介绍了制造结构的设计和冷验测量的电磁和颗粒模拟。
We present the design, fabrication, and low power testing of a THz-driven field emission electron gun. The two cell standing-wave gun is designed to be powered by a 110 GHz gyrotron and produce 360 keV electrons with 500 kW of input power. Several gun structures were fabricated using a high precision diamond turned mandrel and copper electroforming. The field emission source is a copper tip with a 50 $μ$m radius inserted halfway into first cell. The frequencies of the cavity resonances were mechanically tuned using azimuthal compression. This work presents electromagnetic and particle simulations of the design and cold test measurements of the fabricated structures.
