| 摘 要： | 带状注器件在高频率、高功率方向发展潜力巨大，而多间隙腔是提高效率和功率容量的有效手段。本文提出了一
种带状注速调管多间隙输出腔，并设计了一种Ka波段带状注速调管输出腔。此输出腔结构可以获得好的输出耦合特性，
以及理想的电场场形。最后通过MAGIC粒子模拟软件对电子注群聚，能量转换以及输出腔频谱特性等作了仿真和详细分
析，在中心频率获得了稳定的功率输出，互作用效率达到50%以上。

| Abstract: | Sheet beam klystron is a kind of microwave vacuum device, which has great potential to increase power
capability and beam-wave interaction efficiency. In this paper, a multi-gap output cavity sheet-beam klystron is designed and used
in design of the output cavity of a Ka-band sheet-beam klystron. The structure can get a better output coupling characteristics and
a better shape of electric field for better beam-wave interaction. The article also analyzes and introduces the theory of equivalent
circuit for output cavity. Finally, a output power is gotten at the center frequency in the particle simulation, with interaction
efficiency of more than 50%. |
