高峰值功率多注速调管的初步研究

Preliminary research of high peak power multi-beam klystron

高峰值功率速调管因其作为高功率微波源而受到各国的重视。采用单电子注方案的高峰值功率速调管存在许多难以克服的问题,如工作电压很高,输出效率偏低,系统体积偏大等。对高峰值功率多注速调管进行了初步的研究,重点研究了S波段50 MW多注速调管的电子光学系统和高频互作用系统。研究表明,在与单注速调管相同的功率电平下,多注速调管的工作电压明显降低,输出效率明显提高,同时,这种管型也存在结构复杂、电子注聚焦和消除非工作模式困难等技术问题。

The ghigh peak power klystron works as a high power microwave source and is receiving much recognition. The single beam high power klystron has experienced many drawbacks that are unable to overcome, such as the high operating voltage, the low output efficiency, and the bulky system volume etc. In this paper, the high peak power Multi-Beam Klystron（MBK） was preliminarily researched and the electron optics system and RF interaction system of an S-band 50 MW MBK were studied. The results show that the MBK has many advantages compared with the single beam klystron. Under the same power level, the MBK reduces the operating voltage and improves the efficiency greatly.
