一、引言当前,由于大型物理研究设备(诸如:直线粒子加速器、储能环、受控热核聚变等离子体加热试验、电离层雷达诊断学等)方面的迫切需要,要求研制在超高频波段能产生极高输出功率的速调管。已经投入使用或正在设计的设备,功率要求为连续波数百千瓦或脉冲功率100兆瓦(长脉冲或高工作比下)。对要求更高高频功率的设备,正在讨论之中。 I. INTRODUCTION At present, due to the urgent need in the field of large-scale physics research equipment such as linear particle accelerator, energy storage ring, controlled plasma thermo-nuclear plasma heating test, ionospheric radar diagnosis, etc., A klystron that produces very high output power. Equipment already in use or under design, with power requirements of hundreds of kilowatts continuous wave or 100 megawatts (long pulse or high duty cycle). Equipment for which higher frequency power is required is under discussion.
