摘要

为了实现千兆瓦级的微波火箭电源，降低回旋管的成本是降低波束站实现门槛的解决方案之一。本研究设计并研制了一种亚毫瓦级的回旋管，该回旋管适应较小口径的超导磁体。输出功率为600kw，脉冲持续时间为$100\ \mu\ mathm {s}$，频率为94ghz。电子电流由充电电容器组和内部IGBT开关驱动。回旋管与超导磁体对齐，实现了高电效率。

Development of a High Power Gyrotron Prototype for GW-Class Microwave Beam Source Study

To realize the GW-class power source for Microwave Rocket, the cost reduction of gyrotrons is one of the solutions to lower the threshold to realize the beam station. In this study, a sub-MW-class gyrotron which adapted a smaller bore diameter of the superconducting magnet was designed and developed. The output power, pulse duration, and frequency are respectively 600 kW, $100\ \mu\mathrm{s}$, and 94 GHz. The electron current is driven by a charged capacitor bank and in-house IGBT switches. The gyrotron tube was aligned with the superconducting magnet to achieve high electric efficiency.
