线性加速器在更高频率下的持续发展带来了一些技术挑战。其中一个挑战是需要高频放大器来驱动线性化系统。介绍了一种适用于6 GHz或12 GHz驱动频率的48 GHz回旋速调管放大器的设计。回旋速调管中使用的束流是由磁控注入枪提供的，磁控注入枪是采用遗传优化设计的。回旋速调管互作用电路的设计与援助的粒子在细胞（PIC）模拟研究，预测2兆瓦的输出功率在48 GHz的增益为35 dB和效率为38%。本文总结了前面的工作的相互作用电路和附加相位稳定性分析，以及真空窗口，输入耦合器和集电极的设计和分析。
The continued development of linear accelerators at higher frequencies poses several technological challenges. One such challenge is the requirement for high-frequency amplifiers to drive linearization systems. Presented in this article is the design of a 48 GHz gyroklystron amplifier appropriate for application in a harmonic linearizer for a 6 GHz or 12 GHz drive frequency. The beam used in the gyroklystron is provided by a magnetron injection gun (MIG), which has been designed using genetic optimization. The gyroklystron interaction circuit was designed with the aid of a Particle-in-Cell (PIC) simulation study which predicted 2 MW of output power at 48 GHz with a gain of 35 dB and an efficiency of 38%. This article summarizes the preceding work on the interaction circuit and MIG with additional phase stability analysis as well as presenting the design and analysis of vacuum windows, an input coupler, and the collector.
