Ⅰ、引言本文所要讨论的是,钼在大功率电子枪中的应用以及元件精密深引伸工艺的某些技术问题。大功率行波管的研制及其对大功率电子枪的相应的需要,要求对用于制造电子枪的材料和技术进行严格的审查。电子枪的设计规范必须考虑到材料要容易去气,无污染,并能够在 I. INTRODUCTION This paper discusses the application of molybdenum in high-power electron gun and some technical problems of precision deep drawing process. The development of high-power traveling-wave tubes and their corresponding needs for high-power electron guns require rigorous scrutiny of the materials and techniques used to make the electron guns. Electron gun design specifications must take into account the material to be easy to go air, no pollution, and can be
