The RF power production efficiency is one of the major concerns in the 3-TeV Compact Linear Collider (CLIC) Drive Beam Accelerator, as it is responsible for almost 50% of the entire accelerator complex power consumption. The klystron technology with dc post acceleration of the prebunched beam was reconsidered recently, as an attempt to develop a technological solution for the high efficiency, high power ${L}$ -band multibeam klystrons (MBKs). In this article, the modeling and design study of the CLIC MBK with two-stage (TS) configuration is presented. The CLIC TS MBK performance validation has been done using the sophisticated 3-D particle-in-cell computer simulations of the entire device.

CLIC两级多波束速调管建模与技术设计研究

RF 功率生产效率是 3-TeV 紧凑型线性对撞机 (CLIC) 驱动束加速器的主要问题之一，因为它占整个加速器复合功率消耗的近 50%。最近重新考虑了具有预聚束直流后加速的速调管技术，以尝试为高效、高功率 ${L}$ 波段多束速调管 (MBK) 开发技术解决方案。在本文中，介绍了具有两级 (TS) 配置的 CLIC MBK 的建模和设计研究。CLIC TS MBK 性能验证是使用整个设备的复杂 3-D 细胞内粒子计算机模拟完成的。
