能源消耗是未来大型高能加速器项目的主要关注点，如紧凑型直线对撞机（CLIC），未来圆形对撞机（FCC）和国际直线对撞机（ILC）。因此，微波功率的有效产生最近获得了加速器社区的新关注。为此，我们提出了一个创新的两级多注速调管（TS-MBK）的概念。它结合了非常高的射频功率产生效率（84%）和紧凑且具有成本效益的机电配置。本文介绍了1.0 GHz、24 MW速调管的概念和设计研究。技术新颖性和缓解问题的具体到这个概念进行了说明。TS-MBK的性能已被验证，使用粒子在细胞的计算机模拟。
Energy consumption is a major concern for future large-scale high-energy accelerator projects such as the compact linear collider (CLIC), future circular collider (FCC), and international linear collider (ILC). Thus, efficient generation of microwave power recently gained new attention by the accelerator community. In response, we propose an innovative two-stage multibeam klystron (TS-MBK) concept. It combines a very high RF power generation efficiency (84%) with a compact and cost effective electro-mechanical configuration. This article presents the concept and design study of a 1.0-GHz, 24-MW klystron. The technological novelties and mitigation of issues specific to this concept are described. TS-MBK performance has been validated using particle-in-cell computer simulations.
